Goal: Reasoning regarding inductors
Source: 283-750 LR equivalent at time = infinity
Consider the following circuit.
The switch is closed at t=0. Which circuit is equivalent to this circuit
as t approaches infinity?
(3) Some students misunderstand the statement that inductors behave as a
short circuit after a long time and select #1 or #2.
This item is best used in conjunction with the previous one. Both should
be asked before discussion of either to reveal whether students just
have the behaviors reversed or evidence a more serious problem.
