Express the instantaneous power, Electrical Engineering

Assignment Help:

Q. On a per-phase basis, let v = √2 V cos ωt and i = √2 I cos (ωt - θ).

(a) Express the instantaneous power s(t) in terms of real power P and reactive power Q.

(b) Now consider the energy E associated with the instantaneous power and show that E = Pt, where t is the duration of the time interval in seconds.
