P1 = 1400 W, P2 = 800 W
= 25.28°
Power factor, cos ϕ = cos 25.28° = 0.90
= 25.28°
Power factor, cos ϕ = cos 25.28° = 0.90

Given Information:
- Two wattmeter readings: 1400 W and 800 W
- Balanced 3-phase load
Calculating Total Power:
- Total power consumed by the load can be calculated by adding the readings of both wattmeters.
- Total power = 1400 W + 800 W = 2200 W
Calculating Power Factor:
- Power factor (PF) can be calculated using the formula: PF = (P1 - P2) / (P1 + P2)
- Substituting the values: PF = (1400 - 800) / (1400 + 800) = 600 / 2200 ≈ 0.2727
Calculating Power Factor Angle:
- The power factor angle (θ) can be calculated using the formula: θ = cos^(-1)(PF)
- Substituting the power factor value: θ ≈ cos^(-1)(0.2727) ≈ 73.36 degrees
Interpreting the Result:
- Since both wattmeter readings are positive, the power factor angle should be in the first quadrant.
- Power factor angle in the first quadrant ranges from 0 to 90 degrees.
- Therefore, the power factor is between 0.9 to 0.91, as the calculated angle of 73.36 degrees falls in this range.
