Internal Resistance of a Battery
HOW DOES IT WORK? Batteries are used in electrical circuits to provide energy per unit charge moving through the circuit. The emf of the battery is measured on a voltmeter connected in parallel with the battery – the battery is not connected to an external circuit. Emf is defined as the maximum amount of work per unit charge that a battery can do.
