Question

what is meant by electric resistance of a conductor? what is SI unit of resistance? ​

Answer 1

$\huge {\underline{\red {Answer}}}$

The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. The S.I. unit of electrical resistance is the ohm (Ω). The resistance (R) of an object is defined as the ratio of voltage across it (V) to current through it (I).
