Switch using Transistor

This is part of the starter blog for Transistor Basics. Check out here to see all of them.

The most basic task for which a transistor is used is as a switch. These are mainly used with microcontrollers to draw more current from the source to drive higher current components(say relay/small motors) that can’t be run by the low current provided by the microcontroller pins.
