Question

Calculate the potential difference required across a conductor of resistance 5 ohms to make a current of 1.5a flow through it

Answer 1

Explanation: Here,

                      resistance( R )= 5 Ω

                      current( I )= 1.5 A

As we know, Potential difference( V )= IR

                                                                = 1.5*5

                                                                = 7.5 V

Answer 2

Given:

Resistance=5 Ohms

Current=1.5 A

To find:

The potential difference required across the conductor

Solution:

The potential difference required across the conductor is 7.5 V.

We can obtain the value by following the given steps-

We know that the potential difference required across the conductor can be calculated as a product of the resistance and current flowing through.

So, the potential difference=Resistance×Current

The resistance=5Ω

The current flowing=1.5 A

On putting the values, we get

Potential difference across the conductor=5×1.5

=5×15/10

=15/2

=7.5 Volt

Therefore, the potential difference required across the conductor is 7.5 V.
