The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.

The key principle behind the operation of a transformer is Faraday’s law of electromagnetic induction. When an alternating current (AC) flows through the primary winding, it produces a changing magnetic field. This changing magnetic field induces a voltage in the secondary winding, according to Faraday’s law. The induced voltage in the secondary winding is proportional to the ratio of the number of turns in the secondary winding to the number of turns in the primary winding, known as the turns ratio. This allows transformers to step up or step down the voltage between the input and output circuits.

Transformers work on the principle of energy conservation. The power delivered to the primary winding is equal to the power delivered to the secondary winding. Therefore, by adjusting the turns ratio, transformers can either increase (step up) or decrease (step down) the voltage level while maintaining the same power. This makes transformers essential in power transmission and distribution systems, as they enable efficient transfer of electricity over long distances.
