The Basics of Capacitors: Working Principles and Applications
Understanding the working principle of capacitors and their applications in circuits and electrical systems.
00:00:05 This video explains how capacitors work, where they are used, and why they are important. Capacitors store electrical charge and can quickly release energy. They are commonly used in electronic circuits.
💡 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.
00:01:13 Explained: How capacitors work as reservoirs of energy, releasing it to power circuits and maintain continuity during interruptions. The basic structure includes conducting plates separated by a dielectric material.
💡 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.
00:02:21 This video explains how capacitors work and their basic principles, involving the movement of electrons and the storing of energy.
💡 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.
00:03:30 An explanation of how capacitors work and the principles behind them, including the measurement of voltage and the attraction of charged electrons.
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.
