# RMS Current

August 16th Fact-of-the-DayRMS is an abbreviation
for the 'root mean square' mathematical process of determining
the effective value of an alternating current. The RMS or effective value
of a current is by definition such that the heating effect is the same
for equal values of alternating- or direct-current. However, the wattage
found by multiplying the average voltage by the average current is not
the same as the RMS voltage times the RMS current for pulsating direct-current.
The product of average voltage and average current in a pulsating direct-current
circuit is sometimes called 'DC watts.' *©2004 Martek International All
