What is Ohm's Law?: Definition with Example

Ohm’s Law: If physical conditions like temperature, intensity of light etc. remains  unchanged then electric current flowing through a conductor is directly proportional to the potential difference across its ends. If V is the potential difference across the ends of conductors and I is the current through it, then according to Ohm,s Law

V is directly proportional to I or V=RI

R is a constant called resistance of conductor

A force, such as friction, that operates opposite the direction of motion of a body and tends to prevent or slow down the body's motion.  A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms.
