<p>An inductor of self inductance 100 mH, and a bulb are connected in series with an a.c. source of rms voltage 10V, 50 Hz. It is found that effective voltage of the circuit leads the current in phase by&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><mfrac><mi mathvariant="normal">&#960;</mi><mn>4</mn></mfrac></math>. Calculate the inductance of the inductor used and average power dissipated in the circuit, if a current of 1A flows in the circuit.</p>
