Answer:
When in an amplifier circuit only one transistor is used for amplifying a weak signal, the circuit is known as single stage amplifier.
However, a practical amplifier consists of a number of single stage amplifiers and hence a complex circuit. Therefore, such a complex circuit can be conveniently split into several single stages and can be effectively analysed.
The above fig. shows a single stage transistor amplifier.
When a weak a.c. signal is applied to the base of the transistor, a small base current starts flowing in the input circuit.
Due to transistor action, a much larger (β times the base current) a.c. current flows through the the load Rc in the output circuit.
Since the value of load resistance Rc is very high, a large voltage will drop across it.
Thus, a weak signal applied
