In a two stage RC coupled amlifier the rransistor are identical and a common power supply is used.
the output is provided to the first stage of the amplifier wher it is amplified and this output is uses as a input for the sexound stage this is amplified once again by the other transistor in the sexound stage and the final out put is obtain.

∙ 15y agoWhile amplifiers have to have a DC operating power for its internal bias set up. This same bias voltage could be betransferred to the output as unwanted bias voltage, T his voltage can upset the next amplifier bias voltage and so on. a capacitor will block this DC bias voltage and a resistor can be used to restore next amplifier bias point.

∙ 13y agoA: The RC couple amplifier will probalbly not work if fed directly since the first amplifier can be sitting a some DC value which will offset the bias on the second amplifier therefore a capacitor is inserted to remove the DC component and allow AC to pass trough

Loading effect in RC coupled amplifier?
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
Why you need RC coupled amplifier?
Rc coupled amplifier is used where good frequency response required. in case of multistage amplification system,To prevent resistance of one stage to come in parallel with next stage, it is used. we use capacitor as a coupling element between two consecutive stages.
Why RC coupled amplifier is called audio amplifier?
Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.
How do you design a RC coupled bjt amplifier using pnp transistor?
same as you would using an NPN, except the supply voltages are reversed
Circuit diagram of RC coupled amplifier?
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.
What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
What is meant by RC coupled amplifier?
an amplifier, where the resistor and capacitor get coupled to provide high oscillations hence by which amplifications increases at high degrees

Working of Rc coupled amplifier using negative feedback?
As gain increases bandwidth decreases.
Why you need RC coupled amplifier?

Which amplifier has largest bandwidth?
Direct coupled amplifier

Working of RC coupled amplifier?
In a two stage RC coupled amplifier, the two transistors are identical and a common power supply is used. The input is provided to the first stage of the amplifier where it is amplified and this output is used as input for the second stage. This is amplied once again by the other transistor in the second stage and the final output is obtained. There will be a 180 degree phase shift after the first stage amplification which is nullified by the 180 degree phase shift of the second stage amplification.Thus, we obtain an output which is an amplified signal of the input and is in phase with the input signal.
State the application of RC coupled amplifier?
To increase the power gain ,high input impedance,low output impedance,and increase the weaken signal
