\(\mathrm{P}_{0}=\mathrm{V}_{0} \mathrm{l}_{0} \)
\(\Rightarrow 2200=\mathrm{V}_{0} \times 10 \)
\(\Rightarrow \mathrm{V}_{0}=220\, \mathrm{V}\)
\(\because \frac{V_{i}}{V_{0}}=\frac{N_{p}}{N_{s}} \)
\(\Rightarrow V_{1}=2 \times 220=440\, \mathrm{V}\)
Also, \(\quad \mathrm{P}_{0}=\mathrm{V}_{\mathrm{i}} \mathrm{l}_{\mathrm{i}}\)
\(\Rightarrow \mathrm{I}_{\mathrm{i}}=\frac{2200}{440}=5\, \mathrm{A}\)
