Multisim probe/wattage confusion

[lazzer408]

If wattage is vrms squared over R, Why is the multisim wattage probe (on the 4 ohm resistor) showing 50w but RMS voltage is 1/2 that is required to produce 50w?

My guess would be because the transformer winding is across the 4 ohm resistor, thus your meter is really seeing about one ohm.

It's a probe not a meter. The wattage probe should show wattage flowing in the device.

The AC volt meter is showing the correct voltage. The probe is now showing something different then before. I guess I won't trust the probes anymore.

EDIT - The probe is ground referenced and since the ground is through the feedback lines and the CCS. That makes sense. My feedback is differential so that explains it.
