7. Suppose the switch in the circuit shown has been closed for a very long time. What will happen to the current in the 9 N resistor the instant that the switch is opened? (A) It will immediately drop to zero. (B) The current will at first be the same (in magnitude and direction) as when the switch was closed (then decrease over time). 9V (C) The current will reverse direction, but will initially have the same magnitude (which will then decrease over time). 3 mH (D) The current will remain in the same direction, but will suddenly increase in magnitude (then decrease with time). E) The current will reverse direction and suddenly increase (then decrease with time).
