A resistor of

400\Omega

, an inductor of

\frac{5}{\pi}

H and a capacitor of

\frac{50}{\pi}\mu\text{F}

are connected in series across a source of alternating voltage of

140\sin 100\pi t

V. Find the voltage (rms) across the resistor, the inductor and the capacitor. Is the algebraic sum of these voltages more than the source voltage? If yes, resolve the paradox. (Given,

\sqrt{2} = 1.414
