Concept of Real and Reactive Power

Let ‘V’ be the Instantaneous voltage, Let ‘i’ be the Instantaneous current

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
