The Basics of Capacitors: Working Principles and Applications

💡 A capacitor stores electrical charge, similar to a battery, but in a different way.

⚡ Capacitors can charge and discharge energy quickly, making them useful in various electronic circuits.

🔋 Capacitors are commonly used in circuit boards for energy storage and stability.

💡 A capacitor functions as a reservoir and stores energy in an electrical circuit.

🔌 When a capacitor is connected in a circuit, it allows the light to stay on during interruptions in the power supply.

⚡ A capacitor consists of two conducting plates separated by a dielectric material, and is connected to the positive and negative sides of the circuit.

💡 When a capacitor is connected to a battery, the electrons are pushed from the negative terminal to one plate of the capacitor.

💡 The other plate of the capacitor releases some electrons, creating a build-up of electrons on one side.

💡 This build-up of electrons creates a potential difference or a change in voltage, which can be measured using a multimeter.

When the reservoir is empty, the pressure inside is equal to the pressure outside, so the meter reads zero.

The same applies to voltage, where we measure the difference between two points.

With capacitors, we measure the voltage difference across them due to the buildup of electrons.

Electrons are attracted to positively charged plates, creating an electric field.

Placing a small bulb in the circuit provides a path for electrons to flow and power the bulb.

Therefore, electrons flow through the bulb, energizing it, and reach the other side of the capacitor.

⚡️ Capacitors store and release electrical energy.

🔋 Capacitors can be used to provide backup power during interruptions in the electrical supply.

🏢 Large capacitors are used to correct power factor in buildings.

💡 The voltage rating of a capacitor is the maximum voltage it can handle.

🔧 Capacitors are commonly used for power factor correction and to smooth out voltage waveforms

🔄 Capacitors are also used to convert AC energy to DC by rectifying the waveform.

Capacitors are used to release energy in circuits and can create a supply of direct current (DC).

Multimeters can be used to measure the capacitance and stored voltage of a capacitor.

Care must be taken when handling capacitors as they can store high voltage values for a long time even when disconnected from a circuit.

🔑 Capacitors store and release electrical energy.

📏 Capacitor values may differ from the labeled values, requiring accurate measurement.
