It is used to couple output of one stage to input of next stage
A coupling capacitor is used to block the flow of direct current while allowing alternating or signal currents to pass, hence mainly used for joining two stages in radio and amplifier circuits.Also known as blocking capacitor or stopping capacitor. They are also used in substations within a "wave trap" where communication is done by a.c. power line and any d.c. signals need to be attenuated or blocked.

Super capacitor have high capacitance compare to normal capacitor. Super capacitor use two layer of dielectric medium whereas in normal capacitor single medium dielectric. Because of this super capacitor use as alternate power source for RTC when computer is off.
the use of swamping resisters in amplifier is in order to protect the amplifier from high temperatures
paper 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
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
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.
It allows AC current to go through, but blocks DC current.
you need an amplifier for any electronic drumset unless u wanna use earphones
use as coupling in some circuts and and as a filter in rectifier circuit. use as DC current blocking.
I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.

First, the capacitor must be charged. Use a voltmeter, and when it reaches 12 volts, the capacitor is charged. The capacitor should then be installed near the car audio amplifier. Keep the negative wire attached to the battery. Then, a ground wire from the negative post on the capacitor to the car's chassis on the chassis's bare metal ground point. Next, the power wire needs to be disconnected from the amplifier's power input. Connect the wire to the positive post on the capacitor. A new power wire needs to be connected from the capacitor's positive post to the amplifier's power input. Install a 16 gauge wire from the capacitor's remote turn-on post to the amplifier's remote input. Then disconnect the negative wire from the battery.
It can be, but may not be required. Capacitors are used for biasing purposes, to remove DC from inputs, and for filtering in amplifier circuits (just to name a few).
The capacitor is there to block any dc voltage that might be applied to the input terminal, which could cause damage or upset the biassing if it was allowed through to the base.
