<p>(i) Calculate the self-inductance of the inductor.</p>

<p>(ii) When this inductor is used in series with a capacitor of unknown value and a resistor of 10<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;at 300<math xmlns="http://www.w3.org/1998/Math/MathML"><msup><mi>s</mi><mrow><mo>-</mo><mn>1</mn></mrow></msup></math>&nbsp;, maximum power dissipation occurs in the circuit. Calculate the capacitance of the capacitor.</p>
