Question 1 5 pts In the the Figure, given R=314KQ, C=36.3pF, and R V=19.9V. The switch has been open for a long time V for an uncharged capacitor. Find the time constant C (unit in second) of the circuit. Question 2 5 pts In the the Figure, given R=225KQ, C=63.4uF, and V=18.6V. The switch has been open for a long time R for an uncharged capacitor. It is then suddenly V = C closed. Find the maximum charge (unit in uC) on the capacitor. Question 3 5 pts In the the Figure, given R=566KQ, C=53.OuF, and V=21.1V. The switch has been open for a long time R for an uncharged capacitor. It is then suddenly C closed. Find the charge (unit in uC) on the capacitor one time constant after the switch is closed
