This is a handy resistor colour code “calculator” that doesn’t need power supply or to be installed on a PC. As you know most resistors use coloured bands in order to show their value. So basically ...

One of the first things you learn in electronics is how to identify a resistor’s value. Through-hole resistors have color codes, and that’s generally where beginners begin. But why are they marked ...

I once worked with an engineer that often checked his resistors with a multimeter before use. I just assumed that he was just being careful (certainly more careful than I…). Then one day, he asked me ...
