The power factor is given by:
\(cosϕ={P\over S}\)
where, cosϕ = Power factor
P = Active Power
Q = Reactive Power
S = Apparent Power
Explanation
Given that the load is purely resistive.
So, the reactive power (Q) = 0 because the resistor is an energy-dissipating element, not an energy-storing element.
\({Q\over P}=0\)
