Description
The electric potential difference between two points is called voltage. The voltage is equal to the work done per unit charge to move a test charge between two points against static electric field.
Electric potential is given by

Electrical Resistance
The property of a
material that reduces the flow of current through it is called electrical resistance. Every material will have some
amount of resistance except super conductors which have zero resistance. The
materials which have very low resistance are called conductors. The inverse of resistance is called conductance. Resistors are used to control the amount of current passing through conductors. But they dissipate the energy in
