A series circuit consists of a 0.55-H inductor with internal resistance of 8.0 Ω connected in series with a 4.0-Ω resistor, an open switch, and an ideal 12-V battery.   (a) When the switch is closed, what is the initial current through the 4.0-Ω resistor?  [currinit][currunits] (b) What is the current through the 4.0-Ω resistor a very long time after the switch is closed?  [currfin][currunits2]

For the circuit shown in the figure, the inductors have no appreciable resistance and the switch has been open for a very long time. (BONUS 3pts) After the switch has been closed and left closed for a very long time, what is the potential drop across the 60.0-Ω resistor? Explain. [Vlate][Vlateunits]
