A coil of inductance L=5H and resistance...

A coil of inductance `L=5H` and resistance `R=55Omega` is connected in series to the mains alternating voltage of frequency `f=50Hz` in series. What can be the non-zero capacitance of the capacitor (in `muF`) connected in series with the coil, if the power dissipated has to remain unchanged. (take `pi^(2)=10`)
