Question 1:

Name a device that helps to maintain a potential difference across a conductor.

Answer:

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

Question 2:

What is meant by saying that the potential difference between two points is 1 V?

Answer:

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

Question 3:

How much energy is given to each coulomb of charge passing through a 6 V battery?

Answer:

The energy given to each coulomb of charge is equal to the amount of work required to move it. The amount of work is given by the expression,

Potential difference = 

Where,

Charge = 1 C

Potential difference = 6 V

Therefore, 6 J of energy is given to each coulomb of charge passing through a battery of 6 V.
