Expert Solution
Step 1
The switch is an electrical contact that is used for making or breaking a circuit. On closing the switch the circuit is closed and allows the flow of current on the opening of switch the circuit is open, restricting the flow of current. The transistor is a semiconductor device used for the purpose of amplification of electrical power. There are two types NPN, and PNP
