An alternating emf is applied across a parallel combination of a resistance R, capacitance C and an inductance L. If \mathrm{I}_{\mathrm{R}}, \mathrm{I}_{\mathrm{L}} and \mathrm{I}_{\mathrm{C}} are the currents through \mathrm{\mathrm{R}, \mathrm{L}\, \, and\, \, \mathrm{C}} respectively, then the diagram which correctly represents the phase relationship among \mathrm{\mathrm{I}_R, \mathrm{I}_{\mathrm{L}}, \mathrm{l}_{\mathrm{C}} } and source emf \varepsilon, is given by:

Current in inductance I_L lags behind the emf in phase by \pi / 2, current in resistance I_R is in phase with emf, while current in capacitance I_C leads by a phase of \pi / 2.
