An alternating source with a variable frequency, a capacitor with capacitance C, and a resistor with resistance R are connected in series. The gure gives the impedance Z of the circuit versus the driving angular frequency and; the curve reaches an asymptote of 555 Q, and the horizontal scale is set by Lads = 310 rad/s. The gure also gives the reactance XC for the capacitor versus and. What are (a) R and (b) C? Assume ZS = 444 Q. cud (rad/s) A Y (a) Number n UHitS 4* (b) Number I UHltS An alternating source drives a series RLC circuit with an emf amplitude of 6.09 V, at a phase angle of +30.8. When the potential difference across the capacitor reaches its maximum positive value of +5.05 V, what is the potential difference across the inductor (sign included)? Number n Units 1} The gure shows a driven RLC circuit that contains two identical capacitors and two switches. The emf amplitude is set at 12.4 V, and the driving frequency is set at 58.1 Hz. With both switches open, the current leads the emf by 31.0. With switch 51 closed and switch 52 still open, the emf leads the current by 148". With both switches closed, the current amplitude is 453 mA. What are (a) R, (b) C, and (c) L?
