A coil is joined to a 60-Hz, 100-V ac generator. At this frequency the coil consists of an impedance of 8.9 and a reactance of around 6.6?
i) Determine the current in the coil?
ii) Determine the phase angle among the current and the applied voltage? (Compute the angle in degrees, however don’t provide units.)
iii) Determine what series capacitance is needed so that the current and voltage are in phase?
iv) What then is the voltage evaluated across the capacitor?
