Easy MCQ +4 / -1 PYQ · JEE Mains 2023

An alternating voltage source $\mathrm{V}=260 \sin (628 \mathrm{t}$ ) is connected across a pure inductor of $5 \mathrm{mH}$ Inductive reactance in the circuit is :

  1. A $6.28 \Omega$
  2. B $0.318 \Omega$
  3. C $0.5 \Omega$
  4. D $3.14 \Omega$ Correct answer

Solution

$\omega$ = 628 rad/s <br/><br/>$X_{L}=L \omega$ <br/><br/>$$ \begin{aligned} & =5 \mathrm{mH} \times 628 \\\\ & =3.14 \Omega \end{aligned} $$
