## Frequently Asked Questions

To calculate the value of a capacitor based on its code or markings, you need to understand the coding system used by the manufacturer. The coding system also depends upon the type of capacitor. For Example, Ceramic Capacitors consist of three digits. On the other hand, Electrolytic capacitors consist of two or three digits. Each code represents a specific capacitance value. By understanding the value of each code, users can easily calculate the capacitor code. To simplify this process, users can try above-mentioned capacitor color code calculator websites.

The three-digit code on a capacitor is commonly found on ceramic capacitors and represents the capacitance value. Each digit in the code has a specific meaning. The first two digits represent the significant figures of the capacitance value. On the other hand, the third digit represents the multiplier or number of zeros to add to the significant figures.

The capacitor value refers to the numerical quantity that represents the capacitance of a capacitor. Capacitance is a measure of a capacitor's ability to store electrical charge. It determines the amount of charge the capacitor can hold per unit of voltage applied across its terminals. The unit of capacitance is the farad (F).
