The venomous Red-Bellied Black Snake grows to lengths of up to two metres long, and has striking colouration. With stunning red edges to its belly scales and a shiny black back, this snake surely ranks amongst Australia's most stunning venomous snakes.
For other uses, see EMF (disambiguation). Electromotive force, also called emf (denoted E {\displaystyle {\mathcal {E}}} and measured in volts), is the voltage developed by any source of electrical energy such as a battery or dynamo. It is generally defined as the electrical potential for a source in a circuit.
home / study / engineering / electrical engineering definitions / electromotive force. The standard unit of electromotive force (EMF) is the volt. Engineers abbreviate the word âvoltâ or âvoltsâ as V. An EMF of 1 volt (1 V) across a component with a resistance of 1 ohm drives a current of 1A through that component. If the term âelectromotive forceâ seems esoteric, think of it as âelectrical pressure.â Most people call it voltage.
