Q. Which of the following is the resistance of the wire ?
a) R = IV
b) R = I/2V
c) R = V/I
d) R = I/V
Question from BPSC PT 70, 2024
Correct Answer: c) R = V/I
Explanation:
The resistance of a wire is determined using Ohm’s Law, which states:
V = IR
Where:
– V is the voltage across the wire (in volts),
– I is the current flowing through the wire (in amperes),
– R is the resistance of the wire (in ohms).
Rearranging the formula to solve for resistance (R):
R = V/I
Thus, the correct formula for resistance is R = V/I, which corresponds to option c.
