Which of the following gives the resistance of a wire?
જવાબ બતાવો અને સમજૂતી
જવાબ: (C) R = V/I
સમજૂતી
By Ohm's law V = IR, so R = V/I.
- (A) ખોટો
Wrong: IV is power, not resistance.
- (B) ખોટો
Wrong: not a valid relation.
- (C) સાચો
Correct: Ohm's law: R = V/I.
- (D) ખોટો
Wrong: I/V is conductance.
