What is a capacitor used for?
Capacitors are widely used in various electronic circuits, such as power supplies, filters, and oscillators. They are also used to smooth out voltage fluctuations in power supply lines and to store electrical energy in devices such as cell phones and laptops. In short, capacitors have various applications in electronics and electrical systems.
What are the different applications of capacitors?
Let us see the different applications of capacitors. Some typical applications of capacitors include: 1. Filtering: Electronic circuits often use capacitors to filter out unwanted signals. For example, they can remove noise and ripple from power supplies or block DC signals while allowing AC signals to pass through.
How do capacitors work?
Capacitors are connected in parallel with the DC power circuits of most electronic devices to smooth current fluctuations for signal or control circuits. Audio equipment, for example, uses several capacitors in this way, to shunt away power line hum before it gets into the signal circuitry.

For DC circuits, a capacitor is analogous to a hydraulic accumulator, storing the energy until pressure is released. Similarly, they can be used to smooth the flow of electricity in rectified DC circuits in the same way an accumulator damps surges from a hydraulic pump.
What is a capacitor in Electrical Engineering?
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
Why do capacitors have different capacitances?
Different capacity – capacitors that have the same volume have different capacitances depending on their dielectrics. AC coupling/DC blocking – the capacitor allows only AC signals to pass from one section of a circuit to another while blocking any DC static voltage. They are commonly used to separate the AC and DC components of a signal.
