Compute each part of given question:
Question: A series RLC circuit with a resistance of 350 ohm has capacitive and inductive reactances of 260? and 510?, respectively.
Part A: What is the power factor of the circuit?
Part B: If the circuit operates at 60 Hz, what additional capacitance should be connected to the original capacitance to give a power factor of unity?
Part C: How should the capacitors is connected?
