Maybe the most common applications for very-low-value resistors (i.e., milliohms (mΩ) and below) are current-controlling circuits, where their low value reduces power losses. For these applications, a ...

Keithley Instruments, Inc. has published its seventh edition of the Low Level Measurements Handbook: Precision DC Current, Voltage, and Resistance Measurements. This 250-page paperback reference, ...

Cropico, a division of The Seaward Group, introduced the DO7010 portable digital microhmmeter. The ohmmeter is built to measure low resistance and bond resistance, with a measuring range of ...

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 ...

Megger now offers a digital low resistance ohmmeter that can deliver reliable results when using long test leads. The DLRO2, a 2 Amp handheld tester, is ideal for use in production line testing and ...

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 ...

Copper’s resistivity depends on its crystal structure, void volume, grain boundaries and material interface mismatch, which becomes more significant at smaller scales. The formation of copper (Cu) ...
