Question

30mJ work is to be done in moving a charge of 100C across two points in an electric circuit . what is the potential difference between these points.​

Answer 1

Explanation:

1 mega joule = 1000000 joule then

30 mega joule = 30x 1000000= 30000000

So:

100 C charge flow across two point.

∆V= W/Q= 30000000/100

= 300000 Volt.

Thank you.

Answer 2

Explanation:

3×10^5 V is the right answer are potential difference between this.
