Q152 / 160 · TS EAMCET 2023 (12 May Shift 1) · Physics

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
    $90 ^\circ$
  • Correct answer
    D
    $60 ^\circ$

Solution

Power Factor $=\frac{1}{2}$ $\begin{aligned} & \Rightarrow \quad \frac{1}{2}=\cos \phi \\ & \Rightarrow \cos \phi=\cos 60^{\circ} \Rightarrow \phi=60^{\circ}\end{aligned}$

Hence, the correct answer is option: 'D'.
