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 ...

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 marked ...

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 ...

The fun of having a giant resistor-shaped Ohmmeter is that it reads back the resistance by displaying the color code. If you’re not too hot with decoding those bands there’s a helper band to the right ...

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 ...

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} \\ &=& ...
