An ac source is connected in the given circuit. The value of ϕ\phi will be An ac source is connected in the given circuit. The value of φ will be

Options

  1. A30∘30^{\circ}
  2. B45∘45^{\circ}
  3. C60∘60^{\circ}
  4. D90∘90^{\circ}

Correct answer

B. 45∘45^{\circ}

Step-by-step solution

XL=ωLXL=100π×1π=100Ω\begin{aligned} & X_L=\omega L \\ & X_L=100 \pi \times \frac{1}{\pi}=100 \Omega\end{aligned} An ac source is connected in the given circuit. The value of φ will be
tan⁡ϕ=XLR=100100=1ϕ=45∘\begin{aligned} & \tan \phi=\frac{X_L}{R}=\frac{100}{100}=1 \\ & \phi=45^{\circ}\end{aligned}
