Question

1). A transistor can be use as
(a) A half wave rectifier
(b) a full wave rectifier
(c) an amplifier
(d) none of these​

Answer 1

Answer:

c) Amplifier

Answer 2

Transistor

Explanation:

• The transistor can be used in following ways-

        Transistor as a amplifier

       Transistor as a switch

        Transistor as a oscillator

        Transistor as a inverter

• Transistor as an amplifier- When transistor act as an amplifier then it used to raise the strength of a weak signal.
• Transistor as an oscillator- When it act as an oscillator then it is used to produce the oscillations of any requisite frequency.
• Transistor as a switch- It can act as a switch to opening and closing of circuit.
• Transistor as a inverter- It can act as a inverter when it is used to convert ac current into dc current.

Therefore, option(c) is correct i.e. A transistor can be use as an amplifier.
