The figure shows a driven RLC circuit that contains two identical capacitors and two switches. The emf amplitude is set at 11.8 V, and the driving frequency is set at 63.4 Hz. With both switches open, the current leads the emf by 30.5°. With switch S₁ closed and switch S₂ still open, the emf leads the current by 14.6°. With both switches closed, the current amplitude is 439 mA. What are (a) R. (b) C, and (c) L? (a) Number (b) Number (c) Number TH Units Units Units L

A 15-F AC capacitor is connected in series with a 50 resistor. The capacitor has a voltage rating of 600 WVDC. The capacitor and resistor are connected to a 480-V, 60-Hz circuit. Is the voltage rating of the capacitor sufficient for this connection?
You find that a 25-F capacitor connected to 480 VAC is defective. The storeroom has no capacitors with a 480-VAC rating. However, you find two capacitors rated at 50 F and 370 VAC. Can these two capacitors be connected in such a manner that they can replace the defective capacitor? If yes, explain how they are connected and why the capacitors will not be damaged by the lower voltage rating. If no, explain why they cannot be used without damaging the capacitor.
