Answer 1

Answer:

1. potential difference is defined as the work is done in one coulomb of charge.
2. It's SI unit is Volt
3. Expression. - V= W/Q
4. second answer is 12.5 V
5. The rate of flow of charge is called electric current.
6. SI Unit =. Amperes
7. Expression= Q/T where q represent charge and t represent time
8. -
9. voltmeter is a device which is used to measure potential difference. it is connected in parallel where as ammeters is a device which is used to measure flow of the current. it is connected in series.
10. Current flow in a wire in convectional direction i.e. from negative terminal to positive terminal.

hope this will help you
