Extracted text: RC Circuit: Dis-Charging We now continue the problem when the switch has been closed for a very long time, and the capacitor is now fully charged. At time t = 0, the switch is re-opened. Begin the problem by re-drawing the circuit for t → o. T = ms 4. Determine the time constant, t, of the discharging circuit in milliseconds [ms]. 5. Determine Q(topen), the charge on the capacitor at the time topen us (in microseconds) after the switch was re-opened, in microcoulombs. e(topen) = 6. Determine I2 switch has been opened) in milliamperes [mA]. A positive value for the current is defined to be in the direction of the arrow shown the maximum current that flows through resistor R2 (after the max 12, max mA
