An ac series circuit has an impedance of 196 ? , and the phase angle between the current and the voltage of the generator is ? = -72°. The circuit contains a resistor and either a capacitor or an inductor. Find
(a) the resistance R and
(b) the capacitive reactance XC or the inductive reactance XL, whichever is appropriate.
(a) R=____ Ohm
(b) reactance=____ Ohm
