Part a of the drawing shows a resistor and a charged capacitor wired in series. When the switch is closed, the capacitor discharges as charge moves from one plate to the other. Part b shows the amount q of charge remaining on each plate of the capacitor as a function of time. In part c of the drawing, the switch has been removed and an ac generator has been inserted into the circuit. The circuit elements in the drawing have the following values: R = 18 Ω, Vrms = 24 V for the generator, and f = 380 Hz for the generator. The time constant for the circuit in part a is t = 3.0 × 10-4 s. What is the rms current in the circuit in part c? |
