You all must have had a problem while make your projects and searching old pieces of circuits for a particular resistor or a capacitor.
Well , using a multimeter is a good option but it may not be available to most of us, and using it is a bit complicated and I will be posting it in my next instructable on it.
Presently, I will tell you the criterion for calculating the resistance and capacitance.(Only in ceramic capacitors as it is mentioned on electrolytic capacitors)
Step 1: MOTIVATION
I was making a school project and I needed some resistors and capacitors, as the local electronics shop is about 20km from my house saw I started to look in the old circuit boards I have.
As I didn't have a multimeter so I tried to understand the logic behind the codes.
Which I will be telling you.
