The correct answer is:
\(1.67 \mathrm{~A}\)
For a transformer,
\(\begin{aligned}
& V_p I_p=V_s I_s \\
& \Rightarrow I_s=\frac{V_p I_p}{V_s}=\frac{4000 \times 100}{240000} \mathrm{~A}=1.67 \mathbf{A}
\end{aligned}\)
\(\begin{aligned}
& V_p I_p=V_s I_s \\
& \Rightarrow I_s=\frac{V_p I_p}{V_s}=\frac{4000 \times 100}{240000} \mathrm{~A}=1.67 \mathbf{A}
\end{aligned}\)
