Question

3. Calculate the potential difference between the terminals of a battery if
220 J of work is required to be done in transferring
11 C of charge from one terminal of the battery to the
other​

Answer 1

Answer:

As the potential difference between the two terminals of the battery is equal to the work done in moving a unit charge from one terminal to the other. Potential difference V = W/Q = 100 J/20 C = 5 V

Answer 2

Answer:

work done, w = 220 J

charge, q = 11 C

potential difference, v = ?

Using V = W / Q

= 220 / 11

= 20 V
