  • Q1. What is Transformer
  • Ans. 

    A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

    • Transformers are used to increase or decrease the voltage in an electrical circuit.

    • They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.

    • The primary winding receives electrical energy from a power source, while the secondary ...

  • Q2. What is rectifier
  • Ans. 

    A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

    • Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.

    • They are made up of diodes, which allow current to flow in only one direction.

    • Rectifiers can be half-wave or full-wave, depending on the number of diodes used.

    • Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and soli
