So we use a capacitor to release energy into the circuit during these interruptions and that will smooth the power supply out to look more like DC. We can measure the capacitance and stored voltage using a multimeter. Not all multimeters have the capacitance function.
But if we connect a capacitor into the circuit, then the light will remain on during the interruptions, at least for a short duration, because the capacitor is now discharging and powering the circuit. Inside a basic capacitor we have two conductive metal plates which are typically made from aluminium or aluminium as the Americans call it.
Tune a radio into a station, take a flash photo with a digital camera, or flick the channels on your HDTV and you're making good use of capacitors. The capacitors that drift through the sky are better known as clouds and, though they're absolutely gigantic compared to the capacitors we use in electronics, they store energy in exactly the same way.
One of the most common applications of capacitors in large buildings is for power factor correction. When too many inductive loads are placed into a circuit, the current and voltage waveforms will fall out of sync with each other and the current will lag behind the voltage.
The amount of electrical energy a capacitor can store depends on its capacitance. The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor.
If we turned a simple circuit on an off very fast without a capacitor, then the light will flash. But if we connect a capacitor into the circuit, then the light will remain on during the interruptions, at least for a short duration, because the capacitor is now discharging and powering the circuit.
The role of capacitors in power supply and lighting circuits
When a capacitor is used in power supply circuits, its major function is to carry out the role of bypass, decoupling, filtering and energy storage. Filtering is an important part of the role of capacitors. It is used in almost all power circuits.

Do Capacitors Have Resistance. No, capacitors do not have resistance in the same way that resistors do. However, real-world capacitors have an inherent resistance known as Equivalent Series Resistance (ESR). This resistance arises from the materials used in the capacitor''s construction, such as the dielectric and the conductive plates.
