The circuit below is a Class A amplifier.
It is used to amplify alternating current signals
which go to an 8
loudspeaker. It is connected to a supply voltage of 6.0 V DC.
What are the capacitors there for?
What is the base-emitter voltage? Explain what
effect this has on the transistor.
The collector-emitter voltage is about 0.2 V.
Show that the collector-emitter current is about 22 mA.
The base current is 4 mA. What is the current
gain of this amplifier?
