Most precision digital multimeters (DMMs) and many source measurement units (SMUs) offer both two-wire and four-wire resistance measurement capabilities. However, these two techniques are not equally ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

The Wheatstone bridge is a way of measuring resistance with great accuracy and despite having been invented over 150 years ago, it still finds plenty of use today. Even searching for it on Hackaday ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

The boss picked you to design equipment to measure in-circuit resistances on circuit boards as they reach the end of a production line, and a colleague suggested you investigate six-wire measurements.

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

Acceptance test reports can tell you the condition of your cables when they were installed, but they tell you nothing about the present condition. Startup alone can radically change the data ...

Intuition tells us that a wire without defects should have zero resistance. But in the real world all conductors, however perfect, have some resistance. A new study confirms that electrical contacts ...
