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 ...

Lightning protection is a critical aspect of establishments that operate sensitive electrical equipment, especially in the broadcast industry. Tied to this first line of protection against lightning ...

The DMM is arguably the most versatile electrical test instrument we have. Even the most basic model can measure voltage, current, and resistance. You can use the resistance measurement function for ...

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 ...

Devices could eliminate the strong magnetic fields currently required to define the standard unit of resistance ...

A quick calculation: To estimate a battery’s internal resistance, you can use a simple voltage-drop method when the open-circuit voltage, loaded voltage, and current draw are known. For example, if a ...

In Episode 34 of EC&M Tech Talk, Electrical Trainer Randy Barnett covers three main points when it comes to earth resistance, also known as ground resistance. First, the National Electrical Code in ...

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 ...

While ac internal resistance (ACIR) measurements are quite common and somewhat standardized when measuring lithium-ion cells, dc internal resistance (DCIR) measurements are nonstandard and generally ...
