A) \[4\sqrt{7}\,\,A\]
B) 1.0 A
C) \[\frac{4}{7}\] A
D) 0.8 A
Correct Answer: D
Solution :
\[{{i}_{0}}=\frac{{{V}_{0}}}{Z}\,,\] \[Z=\sqrt{{{R}^{2}}+{{(\omega L)}^{2}}}\] \[=\sqrt{{{4}^{2}}+{{(1000\times 3\times {{10}^{-3}})}^{2}}}=5\Omega \] \[{{i}_{0}}=\frac{4}{5}\] \[{{i}_{0}}=0.8A\]You need to login to perform this action.
