Question

What are the different uses of transistors?

Answer 1

Transistors can be used as:

1. Transistor as a switch
2. Transistor as an amplifier
3. Transistor as an oscillator
4. Transistor as an inverter

Transistor as a switch

1. A transistor can be used as a switch to open and close the circuit.
2. PNP and NPN transistors are used as switches.

Transistor as an amplifier

1. A transistor can be used as an amplifier.
2. It is used to amplify the strength of the weak signal.

Transistor as an oscillator

1. A transistor is used as an oscillator to produce continuous undamped oscillations of desired frequencies.

Transistor as an inverter

1. A transistor can also be used as an inverter for converting DC signal into AC signal.
2. Bipolar Junction Transistor (BJT), Field-Effect Transistor (FET), etc are examples of transistors used as inverters.
