Capacitor Code: Color and Alphanumeric Value Coding

In this article, we’ll examine the capacitor code used to indicate the value of capacitors. Capacitors are tiny passive electronic components that store electric charge when there is a potential difference across their terminals. And although there are several types of capacitors, all have the general equation C=Q/V. So their coding standard is the same. […]
