What is resistance? The most common definition of resistance is the opposition to current flow—more specifically the flow of electric charge in a material. The circuit element used to model this ...

This video explains how resistors function and how Ohm’s Law defines the relationship between voltage, current, and resistance in electronic circuits. Resistors are passive components used to control ...

This popular article was originally published in the Jan. 16, 2019, issue of Radio World and Jan. 24, here at the website. Understanding electronics and electronic troubleshooting starts with knowing ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

In all kinds of engineering, we build on abstractions in a kind of inverted pyramid. Lots of people can, for example, design a system using ready-made building blocks on printed circuit boards. Fewer ...

Suited for a wide range of current-sensing applications, the LOB Series of molded axial leaded resistors have power ratings of 1W, 3W or 5W and resistance values down to 0.005(omega). They exhibit ...

How do you know if a resistor is correctly restricting the flow of electricity? Using a multimeter is an obvious answer. However, there is more to it than meets the eye. This article will explain what ...

Although there are several ways to sense current flowing from a source such as a battery, or to a load such as a motor, the current-sense resistor is among the most widely used approaches. There are ...

What’s your favorite value of resistor? 1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are supposed to ...
