EMF

EMF, or electromotive force, is the energy provided by a source like a battery or generator per unit charge as it moves through a circuit. Imagine it as the "push" that drives electric charges to flow through wires and devices. Although called "force," it's not a physical force but a measurement of the potential energy difference that causes current to flow. EMF is measured in volts and represents the maximum potential difference when no current is flowing. It's essential for powering electrical devices and creating the flow of electricity in circuits.
