For example, a capacitor with the code "102K" would have a nominal value of 1,000 pF (or 1 nF), and the actual capacitance could vary by ±10% from this value due to the "K" tolerance code.
So capacitor values are usually given with a prefix. Often you are going to work with capacitors values in pico-farads to micro-farads. To make this simpler to deal with, I''m going to show you how the prefixes work. A prefix is something you put in front of the farad symbol (F). It tells you what you have to multiply the number with. For example, 1 pF means 1 F multiplied …
