Question

1. 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.

2. The given figure is to be designed to pass a wave having a frequency of 3500 cps and block a 2500 cps wave. The series inductor has an inductance of 0.0023 henry. Calculate the capacitance of the series capacitor and the parallel inductor.
