Question

72 joule of work is done by a
battery to cause a flow of 5.4
into 10 to the power 18 electrons
through a conductor for 3 minutes
find the potential difference of the
battery​

Answer 1

Answer:

Potential difference = work / charge

work=72joule ,.

charge= no.of electron×electronic charge ,

charge = 5.4 × 10^18 × 1.6 × 10^-19

, charge = 8.64 × 10^-1. ,

potential difference= 72 /8.64 ×0.1

after solving it p.d. is 83.34 volt

hope it will help you......
