A capacitor with C = 6.00 mF is fully charged by connecting it to a battery that has emf 50.0 V. The capacitor is disconnected from the battery. A resistor of resistance R = 185 Ω is connected across the capacitor, and the capacitor discharges through the resistor. (a) What is the charge q on the capacitor when the current in the resistor is 0.180 A? (b) If the connection to the resistor is completed at time t = 0 , what is the value of t when the current has the value specified in part (a)?

Question

A capacitor with C = 6.00 mF is fully charged by connecting
it to a battery that has emf 50.0 V. The capacitor is disconnected from
the battery. A resistor of resistance R = 185 Ω is connected across the
capacitor, and the capacitor discharges through the resistor. (a) What is
the charge q on the capacitor when the current in the resistor is 0.180 A?
(b) If the connection to the resistor is completed at time t = 0 , what is
the value of t when the current has the value specified in part (a)?
