C) increase the power rating
D) decrease the power rating

Question

Quizplus · Accepted Answer

In a series circuit, a resistor can be used to drop the voltage from the source to a lower value, which is a common application. This is because the voltage across a resistor in a series circuit is directly proportional to its resistance, according to Ohm's law (V=IR), allowing for controlled voltage drops across individual components.
