Measuring output power

[walters]

How do i measure RMS output power?

How do i measure AC voltage output power?

How do i measure the Peak output power?

Just measure the voltage and current

RMS power = RMS V X RMS I

or just P=V X I

Peak = 1.414 X RMS

Output power can be determined from the RMS voltage and the impedance of the load using P = V^2/R

RMS
-----
P (RMS) = ( V (RMS) ^ 2 ) / R (ohms)

PEAK
------
P (PEAK) = ( V (PEAK) ^ 2 ) / R (ohms)
