Some questions about capacitors?

Some questions about capacitors? The capacitor is a very important component of electrical and electronics. Capacitors are needed later in most electronics projects.

What is a capacitor?

1. What is a capacitor?

Its Bengali meaning is the holder which basically stores the electric charge for a moment.

2. What is the role of capacitors in circuits?

Holds the charge for a moment. It can simply be compared to a battery. The battery can hold a charge for a long time. It also does filtering.

3. What type of capacitor should be used in the power supply?

Good quality capacitors must be used in the power supply. Since the components will work depending on the power supply, a good quality capacitor must be connected to the power supply.

The capacitor voltage is used depending on the circuit. If the value of the capacitor is not given in a circuit then the value of supply voltage of the circuit should be fixed and the voltage of the capacitor should be taken. Note that the voltage across the capacitor should not exceed the supply voltage.

4. How do I determine the PF value of a capacitor?

The values ​​of PF capacitors are expressed by code.

Such as

• 101 means its value is 100 pF
• 102 means 1000 pF or 1 nanofarad value thus
• 105 means 100,000 or it is 1 microfarad

This means that the value given in the 3rd cell will be exactly zero. The value of the PF capacitor will be found in it and its practical value will come out after changing it to nano, microfarad.
