The switch has been in position A for a long time. Assume the switch moves instantaneously from A to B at t=0. Click all that apply

40 V + 5 ΚΩ AX B • 2 ΚΩ 10 μF Just before the switch moves from A to B the capacitor voltage is 40V Just before the switch moves from A to B the capacitor voltage is OV + 1 v(0-) is the capacitor voltage right before the switch moves from A to B For t>0 we have a source-free RC circuit V v(0) is the capacitor voltage right after the switch moves from A to B For t>0 we do not have a source-free RC circuit The circuit time constant is 0.02s The circuit time constant is 0.01s v(t)=40*e-50t V At t=∞ (after a long time has passed) the capacitor voltage will be approximately zero volts
