Improper biasing of a transistor circuit produces:
Correct answer: C. Distortion in the output signal
- A. Heavy loading of emitter current
- B. Excessive heat at collector terminal
- C. Distortion in the output signal
- D. Faulty location of load line
Explanation
Transistor Biasing is the process of setting a transistors DC operating voltage or current conditions to the correct level so that any AC input signal can be amplified correctly by the transistor so that output signal is not distorted.To active an transistor, biasing is essential.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
