Which of the following is the resistance of the wire?

Correct answer: (c) R = V/I

Explanation

By Ohm's Law, resistance equals voltage divided by current: R = V/I.

Here R is in ohms (Ω), V is voltage in volts, and I is current in amperes.

Forms like R = IV or R = I/V are dimensionally wrong and do not follow Ohm's Law.
