Explain that a transistor can be used as a switch.

Explain, how a transistor can be used as a switch with the help of a circuit diagram.

How transistor can be used as an oscillator.

With the help of a labelled circuit diagram, explain how an n-p-n transistor can be used as an amplifier in common-emitter configuration. Explain how the input and output voltages are out of phase by 1800 for a common-emitter transistor amplifier.

NPN and PNP bipolar transistors can be used as ON//OFF switch
