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, ...

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 ...

[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 ...

If you’ve got a resistor and you can’t read the color bands (or they’re not present), you can always just grab a multimeter and figure out its value that way. [Giacomo Yong Cuomo] and [Sophia Lin] ...
