Physics - EMI/AC Question with Solution | TestHub

Three alternating voltage sources ${\mathrm{V}}_1=3\sin \omega \mathrm{t}$ volt, ${\mathrm{V}}_2=5\sin \left(\omega \mathrm{t}+{\varphi }_1\right)$ volt and ${\mathrm{V}}_3=5\sin \left(\omega \mathrm{t}-{\varphi }_2\right)$ volt connected across a resistance $\mathrm{R}=\sqrt{\frac{7}{3}}\Omega$ as shown in the figure (where ${\varphi }_1$ and ${\varphi }_2$ corresponds to 30° and $127^{\circ }$ respectively). Find the peak current (in Amp ) through the resistor.
