The common emitter amplifier is used to increase the voltage level of in put signal with small increment in current also but current gain is very less compare to common collector.
for learning biasing download Lt spice open source software.

hi Grossel,

The abbreviation 'cct' is often used to replace 'circuit'.
I do not use it any more because so many words are abbreviated in 'SMS-text speak', it can have many meanings.

it means a circuit, but is it advisable to connect a polar resistor in a common emitter circuit.

What is a "polar resistor"?
Resistors are not polarized.

hi basics
do you mean polar capacitor??
which act as bypass capacitor across emitter
