V (Joule/Coulomb) x I (Coulomb/second) = Power (Joule/sec = Energy/sec). So after multiplication of V by I, Coulomb (unit of electric charge) disappears like a magic and only Energy and time remain. This explains well that Current is not consumed in a load such as a resistor and a light bulb - Kirchhoff's Current law but Energy is consumed, changed to some other form of Energy - conservation of Energy.

I want to call it 'Q' magic, not a Quantum Magic but Charge Magic. We now think it further in terms of Energy.
I wrote in the first article in Asnet Tutorial
"
Energy/Q = V ---> Energy = QV
Energy/ Φ = I ---> Energy = ΦI
Energy x Energy =QV x ΦI = VI x QΦ
= VI x <I x time> x <V x time>
Therefore
Energy2 = (VI x time)2
Energy = +/- VI x time
This helps us to what Power (VI) means in terms of Electric and Magnetic Fields.
In the above explanation Q plays a vital role but Q disappears in the final equation -
Energy/Q = V ----> Energy = QV
Energy/ Φ = I ----> Energy = ΦIThese two equations are actually the same thing although QV seems (electro)static and ΦI seems (magneto) dynamic because
Energy = QV = (I x time) x V
Energy = ΦI = (V x time) x I
We can think of two different conditions - time stops and time is passing. When time stops it becomes static while time is passing it becomes dynamic in either electrically or magnetically. When static the energy becomes potential while when dynamic (the values changes with time) the energy becomes non-static or status of the energy changes.
Energy = QV = (I x time) x V
Although I is a scalar value (Q/t) Qs move (flow) V may unchanged or varies with time when dynamic.
Energy = ΦI = (V x time) x I
V does not move but changes with time and I may unchanged or changes with time and Qs move (flow) when dynamic.
By using the above two equations we can get also
Power = VI = Energy x Energy/QΦ
Here again Q = I x time ,
Very simple. These equations are very simple but they have 'meanings' and maybe 'profound meanings"
