Kinetic energy to electrical energy: how to convert, examples and facts


This post gives you a detailed explanation of how and when kinetic energy is converted to electrical energy and its examples.

Kinetic energy is the energy under its motion and electrical energy is work done or energy consumed by an electrical device. The modification of magnetic flux is generated by comparative shifting in the middle of a coil and magnet. Build a coil at relaxation and build a magnet operating parallel to the coil creating kinetic energy and it converts into electricity.

How is kinetic energy converted to electrical energy?

Tides are brought about by the gravitational pull of sun and moon and earth rotation. Gesticulation of tides generated tidal energy the potency of the water deriving out of mount and plunge of tides is an embodiment of kinetic energy. Tidal capacity encompasses gravitational water power that utilizes the motion of water to thrust a turbine to produce electricity. 

In tidal barrages, over-fall gates upon the barrage jurisdiction water levels and streamline flow to receive the tidal brim to exuberate upon introgression elevation tides and to vacant via electricity generator system on the uninhibited tide. These systems generate electricity from both introvert and extrovert tides by using kinetic energy.

When kinetic energy is converted to electrical energy?

The character of kinetic energy is to spin the wire beneath the magnetic field source. The magnetic field force fascinates the electrons inwards the copper which in succession also line up spin, in each gyration the electrons flirt polarity and origin the electrons to wiggle and generate a rotating magnetic field all over the wire both counter-clockwise and anti-clockwise and generate electricity.

Concurrently as the electric field that grabs the proton and electron coexist inwards the copper atom is emphasized due to the existence of a hardened magnetic field around the wire, net electromotive force potentiality inwards the wire is also generated and this influence among the magnetic and electric field is electricity.

The above process concludes that kinetic energy seeds the swinging electromagnetic field over the wire that can be broached and generate electricity.

Where is kinetic energy converted to electrical energy?

In a traffic scene, the electrokinetic energy road ramp is designed to generate electricity using kinetic energy from traffic this free energy would otherwise be lost.

 The ramp achieves this by employing articulating plates that move up and down under the impact delivered by the vehicles and these plates in turn connected to a mechanism that drives a specially developed flywheel that has very low inertia from rest.

 Which can store a significant amount of kinetic energy this, in turn, drives the generator with an electrical control that alters the magnetic field enabling the mechanism to reach its maximum ramp and produce electricity. A ramp is of an advanced design resulting in the extremely efficient conversion of kinetic energy to electricity.

Kinetic energy to electrical energy formula ?

The formula to convert kinetic energy (1/2mv^2) to electrical energy (Energy = P*t) is,

   [latex]\frac{1}{2}mv^{2} = p\times t[/latex]

Where m is the mass of the object, v is the speed of the object, P is the power and t is the time.

Kinetic energy to electrical energy generator?

As I mentioned above electric generator is a gadget that modified kinetic energy to electrical energy via electromagnetic induction. 

An electrical energy generator contains a rectangular coil, two permanent magnets, and two rings and attaches the axle to a ring, in this generator kinetic energy is transferred to electrical energy by producing electricity.

Two conducting brushes b1 and b2 are get pressed separately in the rings r1 and r2 and the outer ends of these brushes are connected to a galvanometer to show the flow of current these two rings are internally attached to the axle which is used to rotate inside the coil mechanically from outside the system.

When the axle is rotated mechanically (kinetic energy) such that an arm AB is moving up and CB is moving down in the magnetic field produced by the permanent magnet and the coil is rotating clockwise in the external magnetic field and apply Flemming’s left-hand rule to this coil then current is induced along ABCD hence the electricity is generated. This concludes that kinetic energy is converted into an electrical energy generator.

Kinetic energy to electrical energy efficiency

In a wind turbine, the heave forces permit the blade spike of a wind turbine to budge faster than the breeze is operating producing more power and towering – efficiencies. In this process, the kinetic energy is converted as electricity (E.E.) of the wind turbine.

According to the mathematical formula of efficiency,

Efficiency=[latex]\frac{Eout}{Ein}\times 100%[/latex]

Here About is the output energy that is electrical energy and Ennis the kinetic input energy

Therefore,

 Efficiency= E.E./K.E.×100%

A Wind mill

If the blowing wind can turn the wing, we will accept electricity deriving out of the generator which is connected to it. Meanwhile, gaze at the blade intimately the blade consists of an air-wing and transaction comprise of dissimilar appearance and dimensions through the root caps. The air-wing technology constructs the wind turbine blade to revolve this conveys that a heave is created when liquid shift above the air-wing thus winds attain circumrotation and provide kinetic energy transfer electricity via a generator.

The Spinning of magnetic field source

The character of kinetic energy is to spin the wire beneath the magnetic field source. Concurrently as the electric field that grabs the proton and electron coexist inwards the copper atom is emphasized due to the existence of a hardened magnetic field around the wire, net electromotive force potentiality inwards the wire is also generated and this influence among the magnetic and electric field is electricity.

The tides

 When the tides exterior the hurdle move away the water hold on to be set free via turbines creating kinetic energy and generator bring out energy along with water currents and produce electricity.

Road ramp system

The ramp achieves this by employing articulating plates that move up and down under the impact delivered by the vehicles which can store a significant amount of kinetic energy this, in turn, drives the generator with an electrical control that alters the magnetic field enabling the mechanism to reach its maximum ramp and produce electricity.
