WebPower factor can be defined as the ratio of real power (Active power) to apparent power. It can also be defined as the absolute value of the cosine of the phase shift between the voltage and current in an AC circuit. It is denoted by the Greek alphabet λ (Lambda). Power factor (λ) = Active power/Apparent power. = VI.COS φ/ VI. WebNov 5, 2024 · To illustrate the effect of using constrictions with smooth and sharp features on the amplification factor, geometries with circular posts and semi-triangular posts were used.
