Solution: 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 induc

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.
