Question

Current flowing from one end of conductor to another end because of battery connected to it the
flow of charges in this case is due to potential difference across the end of conductor
Which of the points are correct above potential difference?
1. In case of battery where is difference in pressure called electric pressure which is responsible for
charges to flow
2. Due to gravity charges flows inside the conductor
3. Potential difference is work done per unit test charge in moving from one end of the conductor to
another end.

Answer 1

Answer:

3.that is the definition of potential difference
