<p>An ideal inductor of&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><mfrac><mn>5</mn><mi mathvariant="normal">&#960;</mi></mfrac></math>H inductance is connected to a 200V, 50 Hz ac supply.</p>

<p>(a) Calculate the rms and peak value of current in the inductor.</p>

<p>(b) What is the phase difference between current through the indcutor and the appllied voltage? How will it change if a small resistance is connected in series with this inductor in the cirucuit?</p>
