Rubber is basically a milky white coloured colloid which is made of organic polymers named as isoprene. Let us have a look whether rubbers are magnetic in nature or not. Rubber is not magnetic. The reason behind its non magnetic behaviour lies in its constituents which are organic and non magnetic polyisoprenes or elastomers. As …
Electric field is a force of a charge that creates a region around its vicinity where its effect remains. Let us focus on that specific case of the electric field being zero. Electric field is zero when two charges connected through a line have equal electric field intensity. If a particle is moving from one …

Bricks are basically dried clay made rectangular blocks used as building materials. Let us focus on facts related to bricks being insulators. Bricks can act as insulators due to their very low values of thermal conductivity. The very low thermal conductivity of a material signifies that it does not have the capability to conduct heat …
Cotton is a pure cellulose, waxes, fats, pectins and water-made staple fiber that are used to grow in tropical and subtropical regions. Let us focus on the facts related to cotton as an insulator. Cotton can act as an insulator. This is because there are so many air molecules that are trapped in between the …
Rubber is elastic and can return to its original shape after being deformed through stretching and bending. Let us focus on the possibility of rubber behaving like an insulator. Rubber is an insulator as it is a non metal. Non metals do not have free electrons that carry electricity in them. They only have those …
Oil is a natural viscous substance which is obtained from plants,animals and minerals. Let us discuss whether oil conducts electricity or not. Oil does not conduct electricity. Charge carriers that carry current are absent in oil. This makes oil incapable of conducting electricity. Oil is a mixture of long hydrocarbon chains that does not allow …
Covalent compounds share one or more pairs of valence electrons of one atom with another through covalent bond. Let us discuss current conduction is possible or not by the covalent compounds. Covalent compounds are not capable of conducting electricity. Dearth of mobile electrons or charge carriers in the covalent compounds is the reason behind it. …

Nickel(Ni) is a silvery-white metal of atomic number 28. Let us know whether nickel is able to pass electricity or not. Nickel conducts electricity. Nickel is a metal and like other metals it also has free electrons on its surface. These free electrons usually move in a particular direction to carry electricity in the nickel …

Good conductors are those materials that allow current or heat to pass through them very swiftly or those with the minimum resistance. Let us go through their examples. 23 useful good conductors examples are: Silver Copper Gold Aluminum Zinc Mercury Magnesium Molybdenum Cadmium Steel Iron Brass Nickel Sea water Platinum Bronze Water with dirt Lemon …

Brass is an yellowish brown or golden coloured alloy of two metals. Let us discuss whether it conducts electricity. Brass conducts electricity as this metal alloy has 66% of Copper(Cu) present in it. Copper is considered as a good conductor metal of electricity due to its capacity to donate electrons and large value of electrical …
