Additional Problems
Initially, an inductor carries a constant current. Then the current is brought to a new constant value twice as large. After this change, what has happened to the potential difference across the inductor? A) It is larger than before the change by a factor 4. B) It has the same nonzero value. C) It continues to be zero. D) It has decreased.
