Hello guys,
Can you please tell me how I know the initial conditions of this circuit (attached).
It says the switch is left open for a "long" time and then at t=0 its closed. I want to find the current through the 3ohm resistor for t<0.
What I know up to now is that:
the current through the 3ohm resistor should be given by@
i(t) = Ae-t + Be-2t <--- check that this is correct...
but I need two initial conditions to find A and B and thus know how the current changes.
Thanks for your help.
