capacitors can be used for many thing they are one of the most common electrical components they limit current differently at different frequency the higher the frequency the lower resistance. They can also be used to store voltage or build it up to be released all at once in a larger but than could be achieved other wise.
at full input, if the transistor is working, the value of capacitor will be 0.
To connect a Targa capacitor to your amplifier, first ensure the amplifier is turned off and disconnected from power. Connect the positive terminal of the capacitor to the positive power terminal of the amplifier, and the negative terminal of the capacitor to the negative power terminal. Finally, connect the capacitor's ground terminal to a solid ground point on the vehicle. Always double-check your connections and polarity before powering the system back on.
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
If a bypass capacitor is not present in an amplifier, the gain may be reduced due to increased emitter resistance, which can negatively affect the amplifier's frequency response. This could lead to poor performance, particularly in AC signal amplification, as the capacitor typically helps to stabilize the biasing and improve AC gain by providing a low impedance path for AC signals. Additionally, the absence of the bypass capacitor may result in unwanted feedback and reduced overall efficiency of the amplifier circuit.
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.

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.
not sure
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.

It is used to couple output of one stage to input of next stage
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).

Try adding a adding a capacitor.
The capacitor is used to block DC bias from the output, so that only the AC signal is passed. In an audio amplifier, for instance, unwanted DC in the output would cause distortion when fed to a speaker, or could even damage the speaker or amplifier. In the case of interstage capacitors, they block DC so that the output of the first stage does not affect the bias of the second stage.
Without a bypass capacitor it is just equal to Rc
