A quick calculation: To estimate a battery’s internal resistance, you can use a simple voltage-drop method when the ...

Malvern, Pa. — Featuring ultra-low resistance values down to 0.2 milliohms, two new surface-mount Power Metal Strip resistors from Vishay Intertechnology Inc. offers power ratings of 3.0 W and 5.0 W ...

The resistance and conductance of a battery are two parameters that can be used to determine the health of battery strings and identify failed cells. As the two different values have a such a close ...

This multimeter add-on is called the Half Ohm. It allows you to measure small resistance values, and can be used to track down shorts on a PCB. The board acts as a pass-through for both probes. When ...

Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...

Figure 1: Electronic transport in cleaved-edge overgrowth quantum wires. a, Geometry of the CEO device. To create the more complex contacting geometry for a four-probe measurement, we use a pattern of ...
