Why would you use a capacitor?
Capacitors are useful to reduce the voltage pulsation. When the high voltage is applied to the parallel circuit, the capacitor is charged, and on the other hand, it is discharged with the low voltage. While electricity flowing out is alternating current, most of electronic circuits work with direct current.
Do I have to use a capacitor?
Capacitors offer some small amount of protection for amplifiers from potentially damaging under-voltage surges over time if you play loud music regularly. But most of the reason for adding capacitors is to keep your car voltage stable.

How do you know when to use a capacitor in a circuit?
4 AnswersPower Supply Smoothing. This is the easiest and very widely used application of a capacitor. Timing. If you supply power to a capacitor through a resistor, it will take time to charge. Filtering. If you pass DC through a capacitor, it will charge and then block any further current from flowing.
What is the main function of capacitor?
A capacitor is an electronic component that stores and releases electricity in a circuit. It also passes alternating current without passing direct current.
How do you know if a capacitor is working?
How to measure capacitanceUse your digital multimeter (DMM) to ensure all power to the circuit is OFF. Visually inspect the capacitor. Turn the dial to the Capacitance Measurement mode. For a correct measurement, the capacitor will need to be removed from the circuit. Connect the test leads to the capacitor terminals.More items
What if a capacitor reads high?
The high resistance across the capacitor is a sign that the capacitor is faulty. It is reading as if there is an open circuit.
