They are widely used as voltage amplifiers (ie. In the initial stages of public address systems) because of their excellent audio-fidelity over a wide range of frequency. However because of poor impedance matching this type of coupling transistor circuits is rarely employed in final stages
To increase the power gain ,high input impedance,low output impedance,and increase the weaken signal
One of the several uses of an RC coupled amplifier is to amplify the given input signal. It makes use of a sinusoidal input signal.
rc coupling is a coupling that involves capacitor aand resistor
.k/;//
yes
what happens if we remove Rc in RC coupled amplifier
ya
an amplifier, where the resistor and capacitor get coupled to provide high oscillations hence by which amplifications increases at high degrees

Loading of Rc coupled amplifier occurs, if you doesnt use coupling capacitors...... If avoiding input coupling capacitor the amplifier will load the function generator.. For more details go to http://mycircuits9.blogspot.com
As gain increases bandwidth decreases.
