thanks for feed back but i have figured it out. If anyone else needs help with this circuit i'll get u guys started. to find initial current at t=0- the inductor is a short circuit so Io is just the current through the 4.5Ohm resistor.
After the switch is closed to find iL(t) for t >=0 you...
Can anyone please help me slove this example circuit i found.
im having a hard time finding the initial current through the inductor and duno how to deal with the dependent source and inductor after the switch is opened.
