A) \[10.58\text{ }\Omega \]
B) \[12.64\text{ }\Omega \]
C) \[18.85\text{ }\Omega \]
D) \[22.67\,\,\Omega \]
Correct Answer: C
Solution :
(c) \[18.85\text{ }\Omega \] Here, \[L=30\,mH=30\times {{10}^{-3}}H\] \[{{V}_{rms}}=220\,V,\,v=100\,Hz\] Inductive reactance, \[{{X}_{L}}=2\pi vL=2\times 3.14\times 100\times 30\times {{10}^{-3}}=18.85\,\Omega \]
