Power resistors, rheostats (variable resistors), and other electrical loads are useful for testing power supplies and regulators. Though functionally equivalent to a mechanical rheostat, electronic ...

DONGGUAN, GUANGDONG, CHINA, January 20, 2026 /EINPresswire.com/ -- In the dynamic and ever-evolving high-voltage test ...

It’s an unfortunate fact that a resistor can fail under pulse loads. When pulse power is dissipated to the device’s resistive element, it generates heat and increases the resistor’s temperature.

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

An array or bank of load resistors is often required for testing power products, characterization of solar panels, and many other applications that require evaluation under various well-defined loads.

The load control rheostat is used in starting the engine and in controlling the load applied to the engine by the dynamometer during steady state operation. The rheostat controls the current to the ...
