Electrical resistivity is the reciprocal of conductivity. It is the is the opposition of a body or substance to the flow of electrical current through it, resulting in a change of electrical energy into heat, light, or other forms of energy. The amount of resistance depends on the type of material.
Every material has an electrical resistance and it is the reason that the conductor give out heat when the current passes through it. Resistance is a measure of how much an object opposes the passage of electrons. Every material has Resistance. Copper has a low resistance and wood has a high resistance.
