How does a capacitor work in a circuit?
Power supply filtering: Capacitors smooth out the voltage provided by power supplies, reducing any ripples or fluctuations. They act as a buffer, ensuring a stable and reliable power source for the rest of the circuit components. Timing circuits: Capacitors, in conjunction with resistors, can create precise time delays or oscillations in circuits.
What is a capacitor in a circuit?
A capacitor is a two-terminal, electrical component. Along with resistors and inductors, they are one of the most fundamental passive components we use. You would have to look very hard to find a circuit which didn't have a capacitor in it.
Why are capacitors used in electronic circuits?
Well, in electronic circuits capacitors are used in a similar way: If you have a circuit with a microcontroller running some code and the supply voltage to the microcontroller drops for only a split second, the microcontroller stops what it is doing and restarts. That can cause all sorts of problems, so you don’t want this.
What is a capacitor made of?
Capacitors are electronic components that store electrical energy in an electric field. They consist of two conductive plates separated by an insulating material called a dielectric. The conductive plates can be made of metal, such as aluminum or tantalum, and the dielectric can be made of various materials, such as ceramic, paper, or plastic.
