Electronics fundamentals: Identify the full form of EMF in electrical engineering. Voltage is sometimes referred to as EMF. What does EMF stand for in this context? Choose the correct expansion.

Given

• Term: EMF used interchangeably with voltage.

Concept/Approach
EMF 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.

Explanation
EMF = 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 Answer
Electromotive Force.
