the capacitor is store the charge and used as back up
In general, no. You need to use the correct capacitor as designed for the circuit.
paper capacitor
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.
to protect a circuit from damaging
it provides stabilization to oscillator
to bypass current and charge and discharge current
use as coupling in some circuts and and as a filter in rectifier circuit. use as DC current blocking.
When a capacitor is connected to a circuit, the current flow through the capacitor initially increases and then decreases as the capacitor charges up.
