Ohm’s Law and its Application 

Ohm’s Law: Under constant Physical condition, current in a conductor is directly proportional to potential difference across its ends V = IR .Resistance: Resistance of a conductor is directly proportional to its length and its cross-sectional area. Specific resistance: It is defined as the resistance offered by a conductor of unit length and unit cross-section area. Unit of potential difference, current, resistance and resistivity.
