Question

A 1.5m wire carries a 7 A current when a potential difference of 54 V is applied. What is the resistance of the wire?

Answer 1

The resistance of wire will be 7.71 Ohms

Step-by-step explanation:

According to Ohm's Law

V = IR

R= V/ I

Putting the value

R = 54 / 7

R = 7.71 Ohms

Answer 2

R = 7.71 ohms

Explanation:

By ohm's law: R= V/I

where, R = resistance of wire, V = potential difference, I = electric current

Given: V = 54 and I = 7 A

Plug in the above values in the ohm's law, we get

R = 54 V/7 A

R = 7.71 ohms

Hope this will helpful.

Thank you.
