As \mathrm{\mathrm{V}_{\mathrm{L}}=\mathrm{V}_{\mathrm{c}}=300 \mathrm{~V} \text {, }}

and \mathrm{\begin{aligned} &\mathrm{V}=\sqrt{\mathrm{V}_{\mathrm{k}}^2+\left(\mathrm{V}_{\mathrm{L}}-\mathrm{V}_{\mathrm{e}}\right)^2}\\ &\mathrm{V}_{\mathrm{R}}=\mathrm{V}=220 \mathrm{~V} \end{aligned}}

also \mathrm{\mathrm{I}=\frac{\mathrm{V}}{\mathrm{R}}=\frac{220}{100}=2.2 \mathrm{~A}}
