Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail

in which of the following transistor bias methods is the input singel rectified?

A. source biasing

b.voltage divider biasing

c.power supply biasing

d.avc biasing

if a transistor resistor is connected to the emmiter .

A: Transistor to be effective as an linear amplifier it must be operated in its linear load range. The biasing scheme is to insure that the transistor is put in its linear/load range

Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF.

We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.
