The input signal's emitter current goes to the collector current, which then flows through the load resistor RL, causing a high voltage drop across it. This forward bias is maintained irrespective of the signal's polarity.īecause of the low resistance in the input circuit, every minor change in the input signal results in a large change in the output. When a DC bias voltage is provided to the emitter-base junction, it remains forward biased. A transistor functions as an amplifier by amplifying a weak signal.
