Power factor of the circuit Formula and Calculation

cosφ = R/R2 + 2 × π × fd × 1/2 × π × fd × C2

This formula derives from

cosφ = R/Z = R/R2 + (XL - XC )2

where Z is the impedance of the circuit and XL = 2 · π · fd · L and XC = 1 / (2 · π · fd · C) are the inductive and capacitive reactances respectively.
