- 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 have the circiut below with V=60 V, C-575 μF, and R-310 ks2. You move the switch to the left position and let the capacitor become fully charged. With the capacitor fully charged, you flip the switch to the right so that the capacitor is now in a circuit with resistor R. After a time 178.25 s, the charge on the capacitor has decreased by a factor of 2.7. C R V What is the average current going through the resistor in that time? Number A.
