Question

pls help me with this Question ​

Answer 1

Answer:

potential difference= total work done per C charge

so PD=W/charge

100J/20C

=5 V

Answer 2

Answer:

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