Capacitors are passive electronic components that store electrical energy in an electric field. They are widely used in electronic devices for various purposes, such as filtering, smoothing, and energy storage. Checking capacitors using a multimeter is a common task in electronics troubleshooting and repair.
A multimeter is a versatile tool that can measure various electrical parameters, including voltage, current, and resistance. It can also be used to check the capacitance of a capacitor. Capacitance is the ability of a capacitor to store electrical charge. It is measured in farads (F).
