Question

what does an electric circuit mean? name the device that helps to maintain a potential difference across a conductor in a circuit. when do we say that the potential difference across two pointin 1 volt? calculate the amount of work done to move 2 coulomb of charge fraom pont à to b having potencial 110v and 25v respectively

Answer 1

1. An Electric Circuit is a path which electrons from a voltage or current source flow. In an Electric Circuit, Electric Current flows in a closed path. It consists of Electric devices, switching devices, source of electricity, etc. that are connected by conducting wires.

2. A Cell or a Battery or any source of electricity helps to maintain the potential difference across a conductor.

3. If 1J or work is required to move a charge of 1C from one point to another, then it is said that the potential difference between the two points is 1V.
