1.	1 Name a device that helps to maintain a potential difference2. What is meant by saying that the potential difference between two pot3. How much energy is given to each coulomb of charge passing through ass aconductor.is I V?6 V battery?
Answer» 1) A source of electricity such as cell,battery,power supply,etc helps to maintain a potential difference across a conductor. 2)When 1 Joule of work is done to move a charge of amount 1 Coulomb from one place to another, then it is said that potential difference between two pointsis 1 Volt (V). 3)The energy given to each coulomb of charge is equal to the amount of work which is done in moving it. ∴Work done =Potential difference × charge Where, Charge = 1 C and Potential difference = 6 V ∴ Work done = 6×1 = 6 Joule.

1) A source of electricity such as cell,battery,power supply,etc helps to maintain a potential difference across a conductor.

2)When 1 Joule of work is done to move a charge of amount 1 Coulomb from one place to another, then it is said that potential difference between two pointsis 1 Volt (V).

3)The energy given to each coulomb of charge is equal to the amount of work which is done in moving it.

∴Work done =Potential difference × charge

Where, Charge = 1 C and Potential difference = 6 V

∴ Work done = 6×1

= 6 Joule.
