How Transformers Work

Transformers operate based on the principle of electromagnetic induction, discovered by Michael Faraday. The basic operation of a transformer involves the following steps:

  1. AC Voltage Input: An alternating current (AC) voltage is applied to the primary winding of the transformer. The AC voltage creates a varying magnetic field around the primary winding.

  2. Magnetic Induction: The varying magnetic field produced by the primary winding induces a voltage in the secondary winding through a process known as mutual induction. The magnetic field is channeled through a core, which enhances the efficiency of the induction process.

  3. Voltage Transformation: The induced voltage in the secondary winding is proportional to the turns ratio between the primary and secondary windings. The voltage can be increased (stepped up) or decreased (stepped down) depending on the number of turns in each winding.

  4. AC Voltage Output: The transformed voltage is then available at the secondary winding for use in electrical circuits or systems.
