3. Consider the following circuit. The switch is closed for a long time and then opened at time t = 0. 6 kQ 3 V 6 V 1 ΚΩ 2 ΚΩ 5 μF a. Find the current through the 2 k resistor and the voltage across the 5 uF capacitor right before the switch is opened, i.e., at time t = 0. b. Find the current through the 2 k resistor and the voltage across the 5 uF capacitor right after the switch is opened, i.e., at time t = 0+. c. Find the current through the 2 k resistor and the voltage across the 5 uF capacitor after the switch has been opened for a long time, i.e., at time t→ ∞.
