Under construction.
04․ The potential divider biasing is used in amplifiers to
limit the input AC signal going to the base.
reduce DC base current.
reduce the cost of the circuit by limiting the number of resistor
make the operating point almost independent of β.

Under construction.
05․ The Q-point in a voltage amplifier is selected in the middle of the active region because
it gives better stability.
the circuit needs a small.
the biasing circuit then need less number of resistors.
it gives distortions less output.

Under construction.

09․ In a transistor amplifier, the reverse saturation electric current ICO
double for every 10° rise in temperature.
double for every 1° rise in temperature.
double for every 5° rise in temperature.
increase linearly with the temperature.

Under construction.
10․ The CE amplifier circuit are preferred over CB amplifier circuit because they have
lower amplification factor.
larger amplification factor.
high input resistance and low output resistance.
none of these.

Under construction.
