Why does a transistor has three pins? And how do we control the transistor?
How can we install a transistor in a simple circuit? Answer in simple Language. If possible, please tell me all you know about transistors.
The simplest explanation is that a transistor is an electrically controlled switch. There are two kinds of transistors. A field effect transistor (FET) has pins named the Drain, Gate and Source. A bipolar transistor has pins named The Collector, Base and Emitter. The simplest way to think of how it works is like a water valve or electric switch. The water, or electricity goes into the transistor through the Source (or Collector) pin and out through the Drain (or Emitter) pin. The Gate (or Base) pin is the valve handle or electric switch. By putting the right voltage on the Gate of a field effect transistor (or the right current into the Base of a bipolar transistor), you can control the amount of electricity flowing through the Transistor.
Just google "simple transistor circuits" to get sources like this:
