Note that there are only 24 values in each decade — and you probably already know most values. 5 & 6 band resistors While I quickly learned the very useful 4band resistor color codes, I never really ...

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 ...

The colors correspond to the values used in the Resistor Color Code. In the picture above the clock is displaying 5:26 (that’s supposed to be a red band but the camera didn’t pick it up too well).

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 ...

Fold your own resistor value colour wheel Thanks to reader Alan Metcalfe for bringing this to Gadget Master's attention. He describes it as "a simple Mr Spock circular (resistor) calculator, to ...

To protect an LED with a resistor, choose the next larger standard resistor value. preferred values ensure that resistors are widely available and consistent, making it easier to design and ...
