The name given to the driving influence of a voltage source is:
ACentripetal force
BFrictional force
CElectromotive force
DGravitational force
Answer & Solution
Correct answer: C. Electromotive force
1. Voltage sources have a traditional name for their driving effect.
2. There are many different types of voltage sources.
3. The name electromotive force is used, abbreviated emf.
4. Despite the name it is a voltage rather than a force.
