What is the function of a bypass capacitor in an amplifier?
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
Why bypass capacitor of the second stage to disconnect to get the output?
we can use the Out Put Capacitor Ex Kvar
What is purpose of emmiter bypass capacitor in R-C coupled amplifier?
Emitter bypass capacitor is a capacitor which provide low impedance to AC and high impedance to DC . AC is shunt then only DC appears on RC and volage gain increses.
When checked with an ohmmeter how should a properly functioning capacitor respond?
When checked with an ohmmeter, a properly functioning capacitor should initially show a low resistance as the capacitor charges, but then the resistance should increase rapidly to a very high value or infinity as it becomes fully charged. This behavior indicates that the capacitor is not shorted and is capable of holding a charge. If the ohmmeter indicates a constant low resistance, the capacitor may be faulty or shorted. Conversely, if it shows an infinite resistance immediately, the capacitor might be open or defective.
Capacitor from emitter to ground in common emitter circuit is called?
The capacitor is called a bypass capacitor , it provides a low impedence path for AC emitter current to groun.
What happens when the emitter bypass capacitor is shorted?
Then gain becomes equal to hFe and thermal runaway becomes a problem. Further, the reduction of gain as frequency decreases is eliminated, so the stage's operation as a high pass filter is compromised.

What is the output resistance of common emitter amplifier with emitter resistor and without bypass capacitor?
Without a bypass capacitor it is just equal to Rc
What would happen to the output voltage if the capacitor were shorted?
it would get a lot of voltage
Why bypass capacitor of the second stage to disconnect to get the output?
we can use the Out Put Capacitor Ex Kvar
When an Electric motor or Generator is switched on what will make the coil turns the opposite way?
if it is a capacitor start and run motor, this is because of shorted capacitor
Why bypass capacitor is used in common emitter ampifier circuit?
If a bypass capacitor is used the voltage drop across emitter resistance is reduced which in turn increases the gain.....
What is the meaning of a capacitor been shorten?
A shorted capacitor is one where the gap between the plates is damaged, and the plates are touching each other, creating a short circuit.

to bypass current and charge and discharge current
