Question

A potential energy of 5 J is used to move charges across the given battery.




How many charges are being moved?

  1. 0.4 C
  2. 4 C
  3. 2 C
  4. 0.2 C

hintHint:

work done=charge*potential difference.

The correct answer is: 4 C


    work done=charge*potential difference.

    potential difference=Vb-Va
    =-4-6=-10; Work done=5 J
    Charge=5/-10=-0.5C
