What is impedance coupled amplifier?
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.
What is the purpose of a coupling capacitor?
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
What is the purpose of connecting capacitor bank in series with 220 kv feeders?
A: Its purpose is to correct the power factor of the line.
What is the purposeof the capacitor between emitter to ground?
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.
What is need of capacitor and resistor in circuit?
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.

When capacitors are used to shunt current across components such as resistors they are called?
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".
What is the purpose of storing energy using a 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.
What is the purpose of a charge coupled device?
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.

Purpose of capacitor bank on a sub-station electrical room?
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.
What would be the purpose of a headphone amplifier?
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
What is an instrumentation amplifier used for?
A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.
What is the purpose of a bleed resistor in a start capacitor?
its to count the diatamitaion of blood
Purpose of power capacitor bank in car stereo?
hi guys,use of capacitor in car stereo amplifier is really helpful..specially when using an amplifier(s) to drive speakers.the purpose of capacitor is to maintain current level for amplifier(s) so it can perform better and give optimum performance to the speakers. Power capacitor uses the current from main battery and stores it in itself. and whenever car is turned off, amplifier uses the stored power from capacitor.. hopefully this answer will be helpful.
What is the purpose of connecting capacitor bank in series with 220 kv feeders?
A: Its purpose is to correct the power factor of the line.
What is the purpose of a capacitor in a keyboard?
A capacitor on a keyboard serves to decouple key bounces decouple power supplies block DC and many other functions
