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 ...

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 ...

Proper precision calibration resistors are expensive and usually bulky, often in a large box or can. These are overkill for low-cost handheld digital multimeters (DMMs) and LCR Meters, especially when ...
