Question

What is the potential between the terminals of a battery is 250 joule work is done in moving 20 columns from charge of one Another to another terminal

Answer 1

V=w/q

V=250j/20c

V=12.5 volts

Answer 2

Given, W = 250 J

  ⁣   ⁣ Q = 20 V

We know, V = W / Q

  ⁣   ⁣    ⁣V = 250 / 20

  ⁣   ⁣   ⁣   = 12.5 V ...✔
