Question: A device is connected to a (60.0-mathrm{Hz} mathrm{AC}) source for which the emf is given by (mathscr{E}=mathscr{E}_{max } sin (omega t)). If after (5.00 mathrm{~ms})

A device is connected to a \(60.0-\mathrm{Hz} \mathrm{AC}\) source for which the emf is given by \(\mathscr{E}=\mathscr{E}_{\max } \sin (\omega t)\). If after \(5.00 \mathrm{~ms}\) the current is \(30.9 \%\) of its maximum value, is the current leading or lagging the source emf?
