CONCEPT OF REAL AND REACTIVE POWER

Let ‘V’ be the Instantaneous voltage

Let ‘i’ be the Instantaneous current

V = V_m sin ωt

I = i_m 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
