to limit the current and to use it as a back up battery capacitors are used ..
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
A time activated switch could use pneumatics or an resistor capacitor circuit.
not sure
You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.
The shape of a capacitor has no meaning to the circuit. What matters is the capacitance, the voltage rating, and the current rating. 35uf is not the same as 45uf.
To hold and store a charge until it reaches a pre-set value then to discharge it to a circuit all at once.
In general, no. You need to use the correct capacitor as designed for the circuit.

A capacitor is required in electronics when we are charging and frequency circuits.
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.
To find the charge on each capacitor in a circuit, you can use the formula Q CV, where Q is the charge, C is the capacitance of the capacitor, and V is the voltage across the capacitor.
To calculate the charge on each capacitor in the circuit, you can use the formula Q CV, where Q is the charge, C is the capacitance of the capacitor, and V is the voltage across the capacitor. Simply plug in the values for capacitance and voltage for each capacitor in the circuit to find the charge on each one.
To smooth the output of the pulsating DC.
A small capacitor can be part of an integrated circuit.
