Question

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

Answer 1

Given

Current : 2 A

PD : 30

We know the formula that PD = IR

R = $\frac{pd}{i}$

R = $\frac{30}{2}$

R = 15 ohm $Ans$

Answer 2

Answer:

15 ohm

Explanation:

We are given that

Current passing through the conductor=2 A

Potential difference between the ends of the conductor=30 V

We have to find the resistance of the conductor.

We know that

Resistance, $R=\frac{V}{I}$

Substitute the values in the given formula

Then, we get

$R=\frac{30}{2}=15 ohm$

Hence, the resistance of a conductor =15 ohm
