Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

Termination resistors and the ratio units of voltage and power — dB — are interrelated topics. The dB units can refer to voltage or power, and conversions between voltage dB units and power dB units ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

The electrical upgrade of the green carbon facility at the aluminum plant was complete. A myriad of programmable logic controllers (PLCs) and PC-based graphic user interface (GUI) systems replaced the ...
