The resistor color code is a long-standing standard in both the electronics and electrical industries which indicates the value of resistance of a resistor. Ohm’s Law is the foundation of measuring ...

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 ...

Younger electronic engineers may see resistors with old-style color codes to display their values a little less than those from previous years, but if there’s a shibboleth among those who wield a ...

With surface-mount components quickly becoming the norm, even for homebrew hardware, the resistor color-code can sometimes feel a bit old-hat. However, anybody who has ever tried to identify a random ...

The Excel cell formula below calculates the nearest standard 1%-resistor value without using a lookup table or macro. Type or electronically paste the text below into any cell (other than A1). The ...

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 cut-out and make". The Resistor Code Calculator ...
