<p>A resistance of 2 ohms, a coil of inductance 0.01H are connected in series with a capacitor, and put across a 200 volt, 50 Hz supply. Calculate.</p>

<p>(i) the capacitance of the capacitor so that the circuit resonates.</p>

<p>(ii) the current and voltage across the capacitor at resonance. (Take&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><mi mathvariant="normal">&#960;</mi><mo>&#160;</mo><mo>=</mo><mo>&#160;</mo><mn>3</mn></math>)</p>
