In Search of the Zero-Ohm Load
High-wattage resistors often are used as test loads for power transformers. Resistors don't introduce phase shifts, and it's easy to check that a transformer's voltage regulation remains within spec at different rms currents. The effect of various primary tap and secondary loading combinations also can ...

Embedded usually means DC-powered electronics sometimes run by batteries. But military systems are different: They can require high DC voltages (28 VDC for vetronics) and even high-current AC in many airborne platforms. Alternating current is more efficient in these instances and is eventually converted into DC for the electronic suites. ...
