A transistor can be used as an amplifier by enhancing the weak signal’s strength. With the help of the following transistor amplifier circuit, one can get an idea about how the transistor circuit works as an amplifier circuit.
Herein, can a transistor be used as an amplifier?
One of the key characteristics of a transistor is that it can be used as an amplifier. Transistors can act as amplifiers while they are functioning in the active region or when it is correctly biased.

What are audio transistors?
Typically, an audio transistor is an amplification type transistor used to boost weak audio signals, such as in radios, to levels usable by other electronic devices, such as filters, equalizers, other amplifiers, and speakers.
What is difference between transistor and amplifier?
By definition a transistor is only one of the potential semiconductors used. An amplifier is a functional object designed of many components to do a specific job. A transistor is an electronics component that may be used in building an amplifier. Consider a transistor is to an amplifier like a doorknob is to a house.

What is transistor audio power amplifier?
A transistor that is suitablefor power amplification is generally called a powertransistor. It differs from other transistors mostly in size ; itis considerably larger to provide for handling the greatamount of power. Audio power amplifiers are used to delivera large amount of power to a low resistance load.
When transistor is used as an amplifier it is operated in?
Explanation: The transistor can work in three different regions like active region, cutoff region & saturation region. Transistors are turned off while working in the cut-off region and turned on while working in the saturation region. Transistors work as an amplifier while they work in the active region.
When transistor used as an amplifier how it operates?
To use a transistor as an amplifier, its input must be forward biased and output must be reversed biased. So, emitter-base junction must be forward biased and collector-base junction must be reverse biased.
Which transistor is used in audio amplifier?
Since the 1970s, most modern audio amplifiers are based on solid-state transistors, especially the bipolar junction transistor (BJT) and the metal–oxide–semiconductor field-effect transistor (MOSFET).
