Vedclass · Answer

${\rm{I}} = {{\rm{I}}_0}{\rm{sin}}\,\omega {\rm{t}}$

$ \Rightarrow  \mathrm{I}_{0}=\mathrm{I}_{0} \sin \omega \mathrm{t} $

$ \Rightarrow  \sin \omega \mathrm{t}=1 $

$\Rightarrow  \omega \mathrm{t}=\frac{\pi}{2}$

$ \Rightarrow  2 \pi \mathrm{ft}=\frac{\pi}{2}  \Rightarrow \mathrm{t}=\frac{1}{200}, \mathrm{s}=5 \mathrm{\,ms} $
