Question

A coil of 0:84H inductance,and50Ω resistance: is connected in series with a capacitor of 14μ F capacitances " find   the   frequency   for   resonance   and   the   potential differences across the capacitor, across the coil and across the two, when a current of 5A at this frequency, is flowing. (b) find the three potential differences when the same current flows at 60Hz.
