Potential difference between two points equals the
AResistance of the wire between two points
BTotal energy stored in the battery cells
CWork per unit charge moved between the points
DHeat developed in a resistor per second
Answer & Solution
Correct answer: C. Work per unit charge moved between the points
1. The chapter defines V = W / q.
2. Here W is work done in moving charge q between two points.
3. Per unit charge, the work gives the potential difference.
4. So option A is correct.
