How to select a capacitor?
The type of capacitors can be selected from the circuit characteristics. Generally, you can select it by capacitance and voltage in Table-1. About what each type have in common, reliability and price will be considered as well as performances such as frequency characteristics and temperature dependence, etc. shown in Table-2.
What is capacitance of a capacitor?
KEY POINT - The capacitance of a capacitor, C, is defined as: Where Q is the charge stored when the voltage across the capacitor is V. Capacitance is measured in farads (F). 1 farad is the capacitance of a capacitor that stores 1 C of charge when the p.d. across it is 1 V.
What are the characteristics of capacitors in a power supply circuit?
The capacitors C1 and C2 in particular, in the initial stage of single phase 100 VAC and 200 VAC circuits must have a low capacitance and an extremely high ripple current resistance in order to raise the power factor, and compared to capacitors for general power supply circuits, they must have high heat resistance and low loss.
What happens when a capacitor is connected to a voltage supply?
When capacitors in series are connected to a voltage supply: because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.
What does a charged capacitor do?
A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on: the voltage required to place this charge on the capacitor plates, i.e. the capacitance of the capacitor.
What does a capacitor do?
