What does an electric circuit mean ? Name a device that helps to maintain a potential di{ference across a conductor in a circuit. When do we say that the potential difference across a conductor is 1 volt ? Calculate the amount work done in shifting a charge of 2 coulombs from a point A to B having potentials 110 V and 25 V respectively. |
