A capacitor of capacitance C = 1 μF has been charged so that the potential difference between its plates is V0 = 295 V. The capacitor is then connected to a resistor of resistance R = 11.5 kΩ. The switch S is closed, and the capacitor begins to discharge.
Calculate the time T in s after which the charge on the capacitor has decreased to one fourth its maximum value.

You connect a battery, resistor, and capacitor as in (Figure 1), where R = 14.0 Ω and C = 3.00 ×10^-6 F. The switch S is closed at t = 0. When the current in the circuit has magnitude 3.00 A, the charge on the capacitor is 40.0 × 10^−6 C.
At what time t after the switch is closed is the charge on the capacitor equal to 40.0 x 10^-6 C?
When the current has magnitude 3.00 A, at what rate is energy being stored in the capacitor?
