Transistors
The resistors, capacitors, and LEDs are the simple stuff in electrical circuits. Now, let us talk about the first complicated component – the transistor. Transistors are used to build complex electrical systems, such as amplifiers for instance. A simple way to understand transistors is to think of a switch. A basic switch has an “on” and an “off” state. These are controlled by the position of the switch, which is changed manually.


A transistor is a more advanced switch that has multiple output states. Unlike a switch, you cannot change these states manually. The only way to switch the transistor between various states is to run current through it. By controlling the current that flows through the transistor, you can control the output state to achieve the results you desire.
