An impedance coil takes 144 watts at a lagging power factor of 0.6. What value of capacitance and resistance should be connected in series with the coil if the power input to the latter is to remain unchanged and the overall power factor is to be unity (in resonance)? The circuit is energized by a 120 volt, 60 cps source.
