Problem: What is the peak power consumption of a 120-V AC microwave oven that draws 10.0 A?

FREE Expert Solution

The rms voltage and the peak voltage are related by:

Vrms=V02, where V0 is the peak voltage.

Rewriting the equation, the peak voltage:

V0=Vrms2

Similarly, the peak current is:"

i0=irms2

The average AC power:

Pave=12i0V0

Substituting:

Pave=12(irms2)(Vrms2)=12(2)(irmsVrms)
