CONCEPT OF REAL AND REACTIVE POWER
Let ‘V’ be the Instantaneous voltage
Let ‘i’ be the Instantaneous current
V = Vm sin ωt
I = im sin (ωt - Φ)
Radian frequency ω = 2Πf
Transmitter power P = V i
Inductive Load - Absorbs reactive power
Capacitive Load - Generate reactive power
Apparent Power:The product of RMS value of voltage and current
