Electrical Exam Term
Electromotive Force (EMF)
The electrical pressure or voltage produced by a source of energy such as a battery or generator that drives current through a circuit.
Detailed Explanation
EMF is measured in volts and represents the potential energy per unit charge. While often used interchangeably with voltage, EMF specifically refers to the source's ability to drive current, while voltage can refer to the potential difference at any point in a circuit. Understanding EMF is important for generator installations, battery backup systems, and solar photovoltaic systems.
