NEET Physics Power Factor MCQ Question
Type: MCQ-conceptual-Medium
In a series LR circuit XL = R and power factor of the circuit is P₁. When capacitor with capacitance C such that Xₗ = Xc is put in series, the power factor becomes P₂. The ratio P₁/P₂ is:
A
1/2
B
1/√2
C
√3/2
D
2:1
Correct Answer
Option B
Detailed Explanation
The power factor changes due to the addition of the capacitor, which affects the phase angle between voltage and current.
