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.
we can use the Out Put Capacitor Ex Kvar
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.
The capacitor is called a bypass capacitor , it provides a low impedence path for AC emitter current to groun.
A: It is not a bypass it is a negative feedback to effect the input voltage, Bias is when a DC voltage is applied to insure proper operation

Without a bypass capacitor it is just equal to Rc
we can use the Out Put Capacitor Ex Kvar
If a bypass capacitor is used the voltage drop across emitter resistance is reduced which in turn increases the gain.....

to bypass current and charge and discharge current

It passes AC through it and blocks DC
a capacitor that bypasses a BJT's emitter bias resistor so the emitter is at AC ground but has a DC bias voltage on it to set operating conditions. without the bypass, the bias would not stay constant.

Gain in a CE configuration of a BJT is collector resistance divided by emitter resistance, subject to the limit of hFe. The emitter bypass capacitor will have lower impedance at high frequency, so the gain will be higher at higher frequency, making this a high-pass amplifier.
A: A TRANSISTOR gain is determined by current flow on the collector by adding a resistor to the emitter this current flow is reduced by adding or bypassing this resistor with a capacitor the net effect is that this emitter resistor will be reduced in value as frequency increases therefore change gain as a function of frequency input
