List of top Electronics Engineering Questions on AC Circuits

A series LCR circuit consisting of $R = 10\Omega$, $|X_L| = 20\Omega$ and $|X_C| = 20\Omega$, is connected across an a.c. supply of $200\,\text{V}_{\text{rms}}$. The rms voltage across the capacitor is}

If each branch of a Delta circuit has impedance $\sqrt{3}\,Z$, then each branch of the equivalent Wye circuit has impedance
