\mathrm{V=\sqrt{V_R^2+\left(V_L-V_C\right)^2}}

As \mathrm{\quad \mathrm{V}_{\mathrm{L}}=\mathrm{V}_{\mathrm{C}}=400 \mathrm{~V}}
\mathrm{\therefore \mathrm{V}=\mathrm{V}_{\mathrm{R}}}
Reading of voltmeter = \mathrm{100 \mathrm{~V} }
Reading of ammeter,\mathrm{ I_{\text {rms }}=\frac{V_{\text {rms }}}{Z}=\frac{100}{50}=2 A}
