That was my first idea but got confused cause a program showing larger value on right power meter.
It makes sense cause when the difference between them is 180, current flow is highest, power meter shows same power on both sides wich means that power produced on the left side is full acepted on the right. Still confused cause a programs right power meter shows larger value. If I put the difference between them 180 degr. same voltage, freq., I have 4A and power meter 12W and -12W. If power meter shows negative value that means that power source accepting power. I don't see how in first case it can take so much cause on the left is only 3,19W giving. If the 180degr.difference is the answer how much power do I transfer in this case? 12W?
