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 purpose of impedance matching is to provide for the highest efficiency between either the stages of an amplifier circuit or from a device to the amplifier for the same purpose. Impedance matching us used to make the circuits compatible based on electrical characteristics of a particular circuit from one section (or stage) to the next.
A coupling capacitor does the same work as its name suggests, that is coupling one stage of the electronic circuit with another. It does that without passing the DC bias voltages between stages so that these stages are not affected by each other.To block or avoid the flow of D.C and to allow only A.C
A: Its purpose is to correct the power factor of the line.
The purpose of capacitor between emitter to ground is to permit the transis tor to function in the depletion region without the elimination of the Q point.
because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.

A capacitor is typically placed across a resistor for the purpose of shunting either the AC component of a current (as in a transistor amplifier) or transient AC 'spikes', and is referred to as a "bypass capacitor".
The capacitor, in parallel configuration, is a low pass filter, resisting a change in voltage. In series configuration, it is a high pass filter. It can be used in a power supply, to smooth out the ripples in the rectified DC. It can be used to decouple RF transients at the Vcc pin of an IC. It can be used at the input of an AC coupled amplifier to allow amplification while rejecting DC bias. These are only three examples - there are many, many uses.
The purpose of a charged coupled device is to control the movement of electrical charges, usually from within a device to an area where the charge can be manipulated.The charge coupled device is used in mainly digital imaging.

The primary reason for a capacitor bank in an electrical substation is for power factor correction. There may also be some secondary purpose for the capacitor bank but the primary reason is power factor correction.
