TS EAMCET · Physics · Alternating Current
The power factor of an \(\mathrm{AC}\) circuit containing peak current \(2 \mathrm{~A}\) and peak voltage \(1 \mathrm{~V}\) is \(1 / 2\), then the angle between voltage and current is
- A \(30 ^\circ\)
- B \(45 ^\circ\)
- C \(90 ^\circ\)
- D \(60 ^\circ\)
Answer & Solution
Correct Answer
(D) \(60 ^\circ\)
Step-by-step Solution
Detailed explanation
Power Factor \(=\frac{1}{2}\) \(\begin{aligned} & \Rightarrow \quad \frac{1}{2}=\cos \phi \\ & \Rightarrow \cos \phi=\cos 60^{\circ} \Rightarrow \phi=60^{\circ}\end{aligned}\)
