JEE Mains · Physics · STD 12 -7. Alternating current

\(\mathrm{L}=\frac{100}{\pi} \mathrm{mH}, \mathrm{C}=\frac{10^{-3}}{\pi} \mathrm{F}\) અને \(\mathrm{R}=10 \Omega\) ધરાવતો એક શ્રેણી \(LCR\) પરિપથ, \(220 \mathrm{~V}, 50 \mathrm{~Hz}\) \(A.C\). ઉદગમ સાથે જોડવામાં આવે છે. પરિપથનો પાવર ફેકટર_______થશે.

  1. A \(5\)
  2. B \(1\)
  3. C \(45\)
  4. D \(43\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(1\)

Step-by-step Solution

Detailed explanation

\( \mathrm{X}_{\mathrm{c}}=\frac{1}{\omega \mathrm{C}}=\frac{\pi}{2 \pi \times 50 \times 10^{-3}}=10\ \Omega \) \( \mathrm{x}_{\mathrm{L}}=\omega \mathrm{L}=2 \pi \times 50 \times \frac{100}{\pi} \times 10^{-3} \) \( =10\ \Omega \)…
