<p>An alternating voltage of 220V is applied across a device X. A current of 0.22A flows in the circuit and it lags behind the applied voltage in phase by&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><mfrac><mi mathvariant="normal">&#960;</mi><mn>2</mn></mfrac></math>&nbsp;raduab,</p>

<p>When the same voltage is applied across another device Y, the current in the circuit remains the same and it is in phase with the applied voltage.</p>

<p>(i) Name the devices X and Y and,&nbsp;</p>

<p>(ii) Calculate the current flowing in the circuit when the same voltage is applied across the series combination of X and Y?</p>
