i had measure current, voltage and power at my load( bulb ). here are the details:
V=242V
I= 0.36A
P= 101W

so when i calculate the power factor... i realize that the real power is greater than apparent.. how can it be?? can anyone explain it to me.. i using clamp meter to measure current and kill-a-watt meter to measure voltage and real power...

 

Don't resistive loads inherently have a power factor of 1?

 

242 x .36A = 87.12W into a resistive load

"Real" Power measured by Kill-A-Watt: 101W

I think your Kill-A-Watt slipped a digit or your clamp meter jaws weren't shut correctly.
