Sir Isaac Newton worked out the law of electrodynamics.
Yes, "QED" is a commonly used abbreviation for quantum electrodynamics.

power factor means kw/kva
Output Power divided by Power Factor.
There is no disadvantage of unity power factor, because at unity power factor all the electrical power is efficiently utilized by the the load, and at lagging power factor some power is lost in the load's magneticfield.
When looking at power factor, it is the ratio of watts (true power) to VA. The power factor is how we measure power systems. A person with a low power factor like .26 will have a higher electricity bill.
va=xx+3xzy-2xzz
There is no significance to a power factor of 0.82.
