Capacitor Color Codes – How To Read Capacitor Value? Calculator

Generally, the values of capacitance, voltage rating, tolerance and even the polarity (in case of polarized capacitor) are printed on the large size capacitor. On the other hand, for small capacitors like mica and ceramic capacitors, color codes are used to indicate their values (generally) in pF (picofarad).

Capacitors

Capacitors store electric charge. They are used with resistors in timing circuits because it takes time for a capacitor to fill with charge. They are used to smooth varying DC supplies by acting as a reservoir of charge. They are also used in filter circuits because capacitors easily pass AC (changing) signals but they block DC (constant) signals.

Capacitor Color Codes for Identification Chart Capacitors may be marked with 4 or more colored bands or dots. The colors encode the first and second most significant digits of the value, and the third color the decimal multiplier in picofarads. Additional bands have meanings which may vary from one type to another.

How does a capacitor collect a positive charge and a negative charge?

One collects the positive charge, and another gathers the negative. The capacity depends on the size of the capacitor and the dielectric. The higher it is, the larger the plates with more surface area and a higher relative permittivity. This is usually measured in Farads (F), where one Farad equals 1 Coulomb per Voltage (1F 1C/V).

How do you describe a capacitor?

Each capacitor should be accompanied by a name -- C1, C2, etc.. -- and a value. The value should indicate the capacitance of the capacitor; how many farads it has. Speaking of farads... Not all capacitors are created equal. Each capacitor is built to have a specific amount of capacitance.

How does a capacitor discharge?

This is where the capacitance (farads) of a capacitor comes into play, which tells you the maximum amount of charge the cap can store. If a path in the circuit is created, which allows the charges to find another path to each other, they'll leave the capacitor, and it will discharge.
