Question

1. when circuit current decreases, an inductor develops a voltage that

a resists the decrease in current
b assists the decrease in current
c opposes the applied voltage
d subtracts from the applied voltage

Explanation:

According to Lenz's law, an inductor opposes changes in current. When the current decreases, the inductor develops a voltage to resist this decrease. Option b is incorrect as it should resist, not assist. Options c and d are about the relationship with applied voltage, but the key here is the inductor's reaction to current change.

Answer:

A. resists the decrease in current
