IP The switch in the circuit shown in the figure(Figure 1) is open initially.
Part A Find the current in the circuit a long time after the switch is closed. Express your answer in terms of some or all of the variables E, R1, R2, and L.
Part B. Describe the behavior of the lightbulb from the time the switch is closed until the current reaches the value found in part A.
Part C. Now, suppose the switch is opened after having been closed for a long time. If the inductor is large, it is observed that the light flashes brightly and then burns out. Explain this behavior.
Part D. Find the voltage across the lightbulb just before the switch is opened. Express your answer in terms of some or all of the variables E, R1, R2, and L.
Part E. Find the voltage across the lightbulb just after the switch is opened. Express your answer in terms of some or all of the variables E, R1, R2, and L.

A common demonstration of inductance employs a circuit such as
the one shown in the figure (Figure 1) . Switch S is closed, and
the light bulb (represented by resistance R1) just barely glows.
After a period of time, switch S is opened, and the bulb lights up
brightly for a short period of time. To understand this effect,
think of an inductor as a device that imparts an "inertia" to the
current, preventing a discontinuous change in the current...
