[Alex Busman]’s first foray in iOS programming looks like a pretty useful tool. He came up with Ohm Sense, an iPhone app that will take a picture of a resistor and calculate the value based on the ...

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 ...

The values or ratings of electronic components are indicated by the electronic color code that was developed in the early 1920s. It is not only seen in resistors, but also in capacitors, inductors, ...

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 ...

How do you know if a resistor is correctly restricting the flow of electricity? Using a multimeter is an obvious answer. However, there is more to it than meets the eye. This article will explain what ...
