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 ...

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 ...

Resistors have been a part of almost every electronic circuit for well over 100 years. During that time, resistors have taken many forms. You can still find early resistors that resembled glass fuses ...

Younger electronic engineers may see resistors with old-style color codes to display their values a little less than those from previous years, but if there’s a shibboleth among those who wield a ...
