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, ...

Some people look at a venerable resource like resistor color code charts and see something tried and true, but to [Andrew Jeddeloh], there’s room for improvement. A search for a more intuitive way is ...

resistance is measured in ohms (Ω) resistors control current and protect components in electronic circuits. the coloured bands on a resistor is a colour coding system used to identify resistor values ...

Hacker/maker/educator Jimmie Rodgers has a new tattoo. What do you see? Some pretty boxes? Yes, it's that — but also so much more. Let us take you on a tour of its symbolic wonders. First, it's a ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t} &=& \frac{3.9 \times 6.8}{3.9 + 6.8} \\ &=& ...
