When an RLC series circuit is connected to a 120 V rms, 60 Hz line,the rms current in the circuit is 9.60 A and the current leads theline voltage by 45°.
(c) If the inductance in the circuit is 40 mH, find the capacitancein the circuit.
___________ µF
(d) Without changing the inductance, by how much should you changethe capacitance to make the power factor equal to 1?
____________ µF
(e) Without changing the capacitance, by how much should you changethe inductance to make the power factor equal to 1?
____________ mH
