![]() Transformers can also be used for isolation, where voltage is equal to the voltage output, with the individual coils not electrically tied to each other. ![]() This is done through the application of Faraday’s law of induction which states that “the magnitude of the induced voltage in a coil is proportional to the rate of change of the magnetic flux which cuts across the coil”. These are made to increase or decrease the AC voltage between the circuits while controlling the frequency of the current by creating a conductive connection between the two circuits. In other words, it is a voltage control device that is widely used in the distribution and transmission of AC power. ![]() A transformer is a device used in power transmission to transfer electrical energy from one electrical circuit to another, or in multiple circuits at a time.
