Q. Diagram, explain the construction of a single stage RC coupled amplifier?

An RC Coupled amplifier consists of a transistor connected in the emitter configuration with necessary circuit components.

Biasing is done by a potential divider arrangement using resistors R1 &R2. VCC  is applied across the R1-R2 combination .The voltage across the resistor R2 with point 'B' positive is connected to the base of the transistor, thereby forward biasing the base - emitter junction.

The upper end of R1 is at a potential positive with respect to point 'B'. This voltage across the resistor R1 is applied across the base - collector junction to reverse bias that junction. Thus transistor  is biased in the active region.

Collector load resistor RL is in series with the collector .The output voltage is obtained across this resistor

Coupling capacitance Cc is connected at the collector to block dc from appearing at the output.AC signal output is taken through the capacitor CC.
