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 ...

If there’s one thing that will surely blind us, its reading resistor color bands. It doesn’t help that red looks exactly like orange, brown and black are indistinguishable, and different component ...

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 ...

The value of the resistor is 64.3K ohms. The tolerance is ±5% and the tempco is 25 ppm/°C. The first 4 bands determine the value, the fifth band is the tolerance, and the 6th band is the tempco.

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 ...
