WebFeb 10, 2024 · Radiation is energy that comes from a source and travels through space. For example, an electric heater operates by heating metal wires and the wires radiate that energy as heat (infrared radiation). Webv. t. e. In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, [1] [2] denoted or ) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf [3] by converting other forms of energy into electrical energy. [3]

WebRadiation is the means of transferring heat in which no medium is required. The heat can even be transferred in a vacuum. The energy radiated is in the form of a wave and it travels from the hot object. Examples- light and heat energy from the sun reaches us via radiation. Suggest Corrections. WebSep 12, 2024 · Consequently, an emf is induced in each circuit by the changing current in the other.
