What are the 3 types of amplifiers using a transistor?
There are three basic types of amplifier configurations using transistors:
Common Emitter Amplifier
Common Collector Amplifier
Common Base Amplifier
What is meant by an NPN transistor as an amplifier?
An NPN transistor can be used as an amplifier. As it amplifies an input signal by increasing its voltage or current, allowing it to control a larger output signal.
Does a transistor amplify AC or DC?
A transistor can amplify both AC and DC signals. The amplification process in a transistor involves controlling the flow of current through the device using a small input signal. This input signal can be either AC or DC, and the transistor can be configured to amplify the signal accordingly
Why is a transistor called a current amplifier?
A transistor is called a current amplifier because it can be used to amplify the current flowing through it. In an electronic circuit, a transistor acts like a valve that can control the flow of current between two points. By applying a small voltage or current to the transistor's input, the transistor can allow a larger current to flow through its output.
Does the transistor increase current or voltage?
A transistor can be used to increase either current or voltage, depending on how it is configured and the specific application.
