Question

A transistor circuit is used as an amplifier. When a signal is applied to the input of the transistor, the output signal is

Answer 1

Answer:

1. The emitter current caused by input signal contributes the collector current ,which when flows through the load resistors RL, results in a large voltage drop across it.

2. Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.
