In the same way the transformers decreases the voltage down to a lower level and they are called as Step down transformers.Īs stated above a normal transformer will have two windings which are physically separated but magnetically coupled together with the help of a magnetic core. Transformers are used to increase the voltage up to a higher level and they are called step up transformers. This secondary coil will be connected to the load and gets the supply accordingly. The magnetic field produced by the primary induces a voltage into the secondary coil.
The primary coil will get the power from any electrical source like an AC generator. For example in a single-phase transformer there are two coils, a primary and a secondary coil. Mutual induction is the coupling of inductances by their mutual magnetic fields. The Transformers are electromagnetic devices that transfer electrical energy from one circuit to another by principle of mutual induction.
