Here’s a tip from a wizened engineer I’ve heard several times. If you’re poking around a circuit that has failed, look at the resistor color codes. Sometimes, if a resistor overheats, the color code ...

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 ...
