Large amounts of current can damage a circuit. Which of the following changes in a series circuit will result in an increase in current?
A)The voltage is halved and the resistance is halved.
B)The voltage is halved and the resistance is doubled.
C)The voltage is doubled and the resistance is halved.
D)The voltage is doubled and the resistance is doubled.

Question

Quizplus · Accepted Answer

According to Ohm's Law, current (I) is equal to voltage (V) divided by resistance (R). In option C, both doubling the voltage and halving the resistance would increase the current, as the numerator of the fraction increases and the denominator decreases.
