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.

What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
Which amplifier has largest bandwidth?
Direct coupled amplifier
Why gain is fall at high frequency in r-c coupled amplifier?
The gain of an r-c coupled amplifier falls at high frequency because the capacitive reactance of the capacitor tends to zero.
Advantage and disadvantage of RC coupled amplifier?
Electrical Engineering It has a wide frequence response .the gain is constant over the audio freq range which is the region of most important for speech music
Basic theory of two stage RC coupled amplifiers?
connections are to be made per the crkt the main of this crkt is to make strong or to bost the signal comming to the crkt input is given with ac supply and they are connected to resistor and capacitor when the ac suppply is given it contains slight amount of dc supply so to block the dc supply capacitor is used and the dc supply is given at the collector so that resistor present at c and ground gets biased then another capacitor used at c to ground for removing the dc supply then out put seen on cro across collector to ground we get the perfect amplified signal the more we give the coupled amplifer the most amplfed sgnal we get
Working of Rc coupled amplifier using negative feedback?
As gain increases bandwidth decreases.
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
What is loading effect in two stage RC coupled amplifier?
ya
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.
Which amplifier has largest bandwidth?
Direct coupled amplifier
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
State the application of RC coupled amplifier?
To increase the power gain ,high input impedance,low output impedance,and increase the weaken signal
Increasing the capacitance of the coupling capicitor in an RC coupled amplifier has what effect?
the circuit will pass waves of a lower frequency
