## What is voltage drop?

In electrical circuits, voltage drop refers to the decrease in voltage as electric current flows through a component or a series of components. It is an essential concept to understand when analyzing and designing circuits. Voltage drop occurs due to the resistance of the components in the circuit, which causes a loss of electrical energy in the form of heat.

When current flows through a resistor, for example, the voltage across the resistor decreases. This voltage drop is proportional to the current flowing through the resistor and the resistance of the resistor itself. The voltage drop can be calculated using Ohm’s Law, which states that the voltage drop (V) is equal to the current (I) multiplied by the resistance (R): V = I * R.

## The Concept of Series Circuits

To understand voltage drop in a series circuit, it is important to first grasp the concept of series circuits. In a series circuit, the components are connected end-to-end, forming a single path for the current to flow. This means that the same current flows through each component in the circuit.

In a series circuit, the total resistance is equal to the sum of the individual resistances of the components. The total voltage applied across the circuit is divided among the components based on their respective resistances. This division of voltage is what causes the voltage drop across each component.

## The Relationship between Voltage Drop and Series Circuits

In a series circuit, the voltage drop across each component is directly proportional to its resistance. This means that the component with the highest resistance will have the highest voltage drop, while the component with the lowest resistance will have the lowest voltage drop.

To calculate the voltage drop across a specific component in a series circuit, you can use the voltage divider rule. The voltage divider rule states that the voltage drop across a component is equal to the ratio of its resistance to the total resistance of the circuit, multiplied by the total voltage applied across the circuit.

For example, let’s say we have a series circuit with three resistors: R1, R2, and R3. The total resistance of the circuit is the sum of the individual resistances: RT = R1 + R2 + R3. The total voltage applied across the circuit is V. The voltage drop across R1 can be calculated using the voltage divider rule: V1 = (R1 / RT) * V.

By applying the voltage divider rule to each component in the series circuit, you can calculate the voltage drop across each component and analyze the behavior of the circuit.

In conclusion, understanding voltage drop in series circuits is crucial for analyzing and designing electrical circuits. By applying Ohm’s Law and the voltage divider rule, you can calculate the voltage drop across each component in a series circuit and gain insights into the behavior of the circuit.

## The Role of Ohm’s Law in Calculating Voltage Drop

When it comes to understanding and calculating voltage drop in a series circuit, Ohm’s Law plays a crucial role. Ohm’s Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points. This law is essential in determining the voltage drop across individual resistors in a series circuit.

In a series circuit, the total voltage supplied by the power source is divided among the resistors. Each resistor experiences a voltage drop proportional to its resistance. By applying Ohm’s Law, we can calculate the voltage drop across each resistor and understand how it affects the overall circuit.

To calculate voltage drop using Ohm’s Law, we need to know two values: the resistance of the component and the current flowing through it. The formula for calculating voltage drop is:

`Voltage Drop = Current × Resistance`

By knowing the current flowing through a resistor and its resistance, we can determine the voltage drop across it. This information is valuable in analyzing and troubleshooting series circuits.

## The Importance of Knowing the Total Current in the Circuit

To accurately calculate voltage drop in a series circuit, it is crucial to know the total current flowing through the circuit. The total current is the sum of the currents flowing through each component in the circuit.

Knowing the total current allows us to determine the voltage drop across each resistor. In a series circuit, the total current remains constant throughout the circuit. This means that the current flowing through each resistor is the same.

To find the total current, we can use Ohm’s Law again. By rearranging the formula, we can solve for current:

`Current = Voltage / Resistance`

By dividing the total voltage supplied by the power source by the total resistance in the circuit, we can find the total current. This information is essential for accurately calculating voltage drop across each resistor.

## The Concept of Resistance in Series Circuits

In a series circuit, resistors are connected end-to-end, creating a single path for the current to flow. The concept of resistance is crucial in understanding how voltage drop occurs in a series circuit.

Resistance is a property of a component that opposes the flow of electric current. It is measured in ohms (Ω). In a series circuit, the total resistance is the sum of the individual resistances of each component.

To calculate the total resistance in a series circuit, we add up the resistances of all the components:

`Total Resistance = Resistance1 + Resistance2 + Resistance3 + ...`

The total resistance determines the amount of current flowing through the circuit. As the resistance increases, the current decreases, resulting in a larger voltage drop across each resistor.

By understanding the concept of resistance and how it affects the flow of current in a series circuit, we can accurately calculate voltage drop and analyze the behavior of the circuit.

In summary, calculating voltage drop in a series circuit involves applying Ohm’s Law to determine the voltage drop across individual resistors. Knowing the total current in the circuit is crucial for accurate calculations, and understanding resistance helps us analyze the behavior of the circuit. By mastering these concepts, you’ll be well-equipped to tackle series circuit calculations and gain a deeper understanding of electrical circuits.

## Voltage drop in series RLC circuit:

RLC circuit is a particular case of AC circuits. An RLC circuit comprises resistors, capacitors and inductors joined via series. Let us understand the voltage drops across an RLC series circuit through an example.

The circuit has three components drawn below: an R ohm resistor, an L Henry inductor, and a C farad capacitor. We have previously known, the voltage drop across any of them= impedance × current. So,

Voltage drop across the resistor = iR,  the inductor= iXL and the capacitor = iXC where XL= 2πfL and XC = 1/ 2πfC

## How To Calculate Voltage Drop In A Series Circuit- Numerical examples

Problem 1. Three resistors are connected in series with values as R1= 4 Ω, R2= 5 Ω, and R3 = 6 Ω. The circuit is joined with a 15 V power supply. Find out the voltage drops across the resistors.

For calculating the potential drops across R1, R2, and R3, we first need to obtain the current in the circuit. We know, current =net voltage/equivalent resistance

The equivalent resistance Req = R1 + R2 + R3 = 4 + 5 + 6 = 15Ω

Therefore, total current = 15V/15Ω = 1A

Now, we can use ohm’s law (V = IR) for each resistor and find the voltage drops across them.

So, V1 = I x R1 = 1 x 4 = 4V

V2 = I x R2 = 1 x 5 = 5V

V3 = I x R3 = 1 x 6 = 6 V

Problem2. For the below circuit, the voltage drop across the 6-ohm resistor is 12 V. Find out the other voltage drops and compute the total voltage drop or supply voltage.

We know, the voltage drop across any resistor in the series circuit = resistance × total current

If current i flows in the circuit, the voltage drop across the 6-ohm resistor is 6i.

6i = 12 or i = 2 amp

Therefore, voltage drop across the 2 ohm resistor = 2 x 2 = 4 V

Voltage drop across the 4 ohm resistor = 2 x 4 = 8 V

So the net voltage drop or the supply voltage = (12 + 4 + 8) = 24 V

Problem 3. The image below depicts an RLC series circuit with the following components: A 120 V, 50 Hz AC supply, A 100-ohm resistor, A 20 μF capacitor, A 420 mH inductor. Calculate voltage drops across all three impedances.

We formerly knew how to calculate voltage drops for a series RLC circuit. The current multiplied by the impedance ( R or XL or XC) gives us the voltage drop. Let us find out XL and XC first.

XL= 2πfL (f is the frequency of the AC supply)

So, XL = 2 x π x 50 x 420 x 10^{-3} = 131.95 Ω

XC = 1/2 x π x 50 x 20 x 10^{-6} }= 159.15Ω

Therefore, net impedance,

Now, for AC circuits, there is an entity called the phase angle. It gives a measure of the angle by which current lags or leads the voltage. Phase angle φ = arctan (XC – XL/R)

φ = arctan(27.2/100) = 15.22°

So, current

Therefore,

Here, current leads the voltage as XC > XL.

Let’s take an example to illustrate this. Consider a branch circuit with two resistors, R1 and R2, connected in parallel. The current flowing through the branch circuit is 2A, and the resistance of R1 is 4Ω, while the resistance of R2 is 6Ω.

To calculate the voltage drop across each resistor:

• Voltage drop across R1 = Current * Resistance of R1 = 2A * 4Ω = 8V
• Voltage drop across R2 = Current * Resistance of R2 = 2A * 6Ω = 12V

Therefore, the total voltage drop in the branch circuit is 8V + 12V = 20V.

### C. Calculating Voltage Drop in an RLC Circuit

To calculate the voltage drop in an RLC circuit, you need to consider the impedance of each component. Impedance is a measure of the opposition to the flow of alternating current (AC) in a circuit and is denoted by the symbol Z.

The impedance of a resistor (R) is equal to its resistance (R), while the impedance of an inductor (L) and a capacitor (C) is given by the formulas:

• Inductive impedance (XL) = 2πfL, where f is the frequency of the AC supply and L is the inductance of the inductor.
• Capacitive impedance (XC) = 1 / (2πfC), where f is the frequency of the AC supply and C is the capacitance of the capacitor.

To calculate the total impedance (Z) of the RLC circuit, you need to consider the impedance of each component. The total impedance is given by the formula:

Z = √(R^2 + (XL – XC)^2)

Once you have calculated the total impedance, you can use Ohm’s Law (V = I * Z) to find the voltage drop across the RLC circuit.

In summary, calculating voltage drop in branch circuits and RLC circuits requires considering the individual voltage drops across each component and the impedance of the circuit. By understanding these principles, you can accurately analyze and design complex electrical circuits.
