Consider a circuit consisting of a 9.0-V battery, a 100.0 μF capacitor, a 60.0 Ω resistor, a switch, and an ammeter wired in series. Initially, the switch is open and the capacitor is totally discharged. The switch is closed, and after a time t, the ammeter shows a value of 0.05 A. Determine the charge Q on the capacitor at time t.

• A. Q = 0.0 C
• B. Q = 100.0 μC
• C. Q = 600.0 μC
• D. Q = 900.0 μC

Answer: (C)
