Question

derivation of ohms law video lecture

Answer 1

v is proportional to I when r is constant
the p d across the ends the terminal is directly proportional to current passing through the conductor.provided at physical temperatures such as heat

v=IR where R is the resistance.or simply the reluctance of flow of electricity through a circuit
the graph for ohmic conductors which satisfy ohms law generally metals have V I graph straight but for non ohmic conductors it is curved .........
want to know about resistivity and conductivity too. comment
