Answer
Correct Answer: Electromotive Force
Explanation
Given
- Term: EMF used interchangeably with voltage.
Concept/ApproachEMF is a standard electrical term meaning the energy provided per unit charge to move charges through a circuit. It is historically called 'electromotive force' even though it is not a mechanical force.
ExplanationEMF = work done per unit charge (measured in volts).It denotes the potential difference generated by a source (cell, generator).
Common pitfalls
- Confusing EMF with magnetic field (B-field).
- Thinking it represents a mechanical force.
Final AnswerElectromotive Force.
