What is the potential difference between two points in a current-carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other?
A
1 ampere
B
1 volt
C
1 newton
D
1 ohm
Correct Option:
B
Explanation
Potential difference is defined as work done per unit charge: V = W/Q. If 1 joule of work is required to move 1 coulomb of charge, then V = 1 J/1 C = 1 volt.
