What is a transformer, what is diode, what is transistor etc

Question

Accepted Answer

A transformer is a device that transfers electrical energy from one circuit to another through electromagnetic induction. A diode is a semiconductor device that allows current to flow in only one direction. A transistor is a semiconductor device used to amplify or switch electronic signals and power.

Transformers are used in power transmission and distribution systems to step up or step down voltage levels.
Diodes are commonly used in rectifier circuits to convert AC to DC.
Transistors are used in amplifiers, switches, oscillators, and voltage regulators.
There are two types of transistors: bipolar junction transistors (BJTs) and field-effect transistors (FETs).
