`P_"time-averaged" = V_"rms" ^2/ "R" `

Enter a value for all fields

The Time Averaged Power (V,R) calculator compute the power based on the RMS voltage and the resistance. 

INSTRUCTIONS: Choose units and enter the following:

• (R) This is the resistance
• (V_RMS) This is the RMS Voltage

Time Average Power (P):  The calculator returns the power in watts.  However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

Time Averaged Power (V,R)

  This equation computes the time-averaged power.

     P = V²/R

Inputs are:

• R - resistance of the load
• V - RMS voltage

Notes

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

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