CBSE Class 10 Science 2020 · Paper 31/4/3 · Question 2
When is the potential difference between two points in a current carrying conductor said to be 1 volt ?
Answer
It is 1 volt when 1 joule of work is done to move 1 coulomb of charge between the two points.
The potential difference between two points of a current-carrying conductor is 1 volt when 1 joule of work is done to move a charge of 1 coulomb from one point to the other, that is, .
