Here,\mathrm{ \mathrm{N}_{\mathrm{p}}=50, \mathrm{~N}_{\mathrm{s}}=200, \mathrm{I}_{\mathrm{p}}=4 \mathrm{~A}, \mathrm{I}_{\mathrm{s}}= ? }
As \mathrm{\frac{\mathrm{I}_{\mathrm{p}}}{\mathrm{I}_{\mathrm{s}}}=\frac{\mathrm{N}_{\mathrm{s}}}{\mathrm{N}_{\mathrm{p}}} or \mathrm{I}_{\mathrm{s}}=\frac{\mathrm{N}_{\mathrm{p}}}{\mathrm{N}_{\mathrm{s}}} \mathrm{I}_{\mathrm{p}}=\frac{50}{200} \times 4 \mathrm{~A}=1 \mathrm{~A} }
