The power factor is given by:
\(cosϕ={P\over S}\)
where, cosϕ = Power factor
P = Active power
Q = Reactive power
S = Apparent Power
Calculation
For purely resistive load, the value of Reactive power (Q) is zero because the resistor is an energy dissipating element, not energy storing element.
\({Q\over P}={0\over 1}=0\)
