Question

A 1.5m wire carries a 3 A current when a potential difference of 74 V is applied. What is the resistance of the wire?

Answer 1

Answer:

24.7 ohms

Explanation:

Given in the question,

electric current = 3 A

potential difference = 74 V

Using ohm's law

V = IR

R = V/I

here,

R = resistance of wire

V = potential difference

I = electric current

plug value in the formula

R = 74/3

R = 24.7 ohms

Therefore, the resistance of the wire is, 24.7 ohms
