Time Averaged Power (V,I)

  This equation computes the time-averaged power.

Inputs are:

• I  -- electrical current
• `V_"RMS` -- RMS voltage

Notes

The picture shows voltage leading current by phase angle, `phi`, which means this is an inductive circuit.

For an arbitrary periodic waveform, the v(t) over a period T,

`V_"RMS" = sqrt(1/T int_0^T [v(t)]^2 dt)`
