The Energy Principle
It is defined with the fact that the change of the energy of system is equal to the work surrounding in addition to heat transfers from the surroundings as well. This principle can be modeled by the equations: (1) ΔE = Q+W. (2) ΔEsystem + ΔE surroundings = 0. You can see that these equations (particularly equation 2) describe Conservation of ...
Transformer
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer''s core, which induces a varying electromotive force (EMF) across any other coils wound around …
