   Jun 5, 2020 · A transformer is an electrical device designed to transfer electrical energy from one circuit to another at the same frequency. It is also referred to as a static machine since it does not have any moving parts. It is used to control the voltage levels between circuits. It has three main parts which consist of two windings and a metallic core ...

   An electric transformer is a piece of equipment that is designed to change the magnitude of AC voltage in a circuit, without altering the frequency, and at a minimum power loss. Power is delivered from its input side to its output side by the process of electromagnetic induction. They are used to transmit power generated at a remote location to ...

   Formulas. For an ideal two-winding transformer with primary voltage V1 applied across N1 primary turns and secondary voltage V2 appearing across N2 secondary turns: V1 / V2 = N1 / N2. The primary current I1 and secondary current I2 are related by: I1 / I2 = N2 / N1 = V2 / V1. For an ideal step-down auto-transformer with primary voltage V1 ...

   A power transformer is a device that converts alternating current from one voltage level to another, either to "step up" or "step down" voltages. The working principle is based on Faraday's law of electromagnetic induction. When an alternating current is applied to the primary coil, a magnetic field is created around the core.

   Transformers step up (increase) or step down (decrease) AC voltage using the principle of electromagnetic induction - mutual induction. A changing current in the primary coil induces an e.m.f in the secondary. Since the e.m.f generated depends on the number of turns, the voltage induced in the secondary can be changed - stepped up or down - by ...
