Electronic color code How to read electronic color codes written on resistors The electronic code is employed to point the values or ratings of electronic elements, like resistors, capacitors, inductors, telecommunications cables et al..The electronic color code was developed in the early 1920s by the Radio Manufacturers Association (now part of Electronic Industries Alliance (EIA)), …
Reading Capacitor codes Let’s learn about reading capacitor codes! Units of Capacitance: The base unit of capacitance is the farad (F). This value is very large for ordinary circuits, so smaller units have been made for measuring general purpose capacitors. 1 µf (microfarad) = 10-6 farads 1 nf (nanofarad) = 10-9 farads 1 pf (picofarad) = …
