Calculate the resistance of a conductor ...

Calculate the resistance of a conductor through which a current of 2A passes, when the potential difference between its ends is 30V.

Text Solution

Verified by Experts

Current through the conductor I = 2A
Potential difference V = 30V
From Ohm's law , `R = (V)/(I)`
Therefore, `R = (30)/(2) = 15 Omega`
