Question

The switch has been in position a for a long time. At t=0, it instantaneously moves to position b. Find the following: a) (8-points) Voltage response b) (8-points) Current response c) (9-points) Evaluate how long after the switch is in position ‘b' does the voltage across the capacitor equal zero. 400 kA b a 2012 90 V + 40 V 60123 0.5 uF
