Question

'The potential difference between two conductors is 1 volt'.Explain the meaning of this statement.

Answer 1

The potential difference between 2 conductor is 1 volt means If you try to move the test charge from one conductor to another then you have to use one Joule of energy or work done will be one Joule.
Because the definition of potential difference is, It is the amount of work done to move test charge from one point to another inside an electric field.
*The definition I have given may not be exact but explains the meaning.

Answer 2

Answer:

Potential difference between two point is said to be 1volt if work done in transferring 1 coulomb of charge from one point to the other point is 1joule.
