In 10 second a charge of 25 c leaves a battery and 200j of energy are delivered to outside circuit as a result, what is potencial difference across battery and what current flows from battery.

Open in App

Solution

potential difference =work done/total charge
=1J/1C
= 200J/25C
=8V
current =charge/time
= 25C/10S
=2.5A
