According to the equation expressed as Ohm's law, which of these would cause the greatest increase in current?
A) doubling both voltage and resistance
B) reducing both voltage and resistance by half
C) doubling voltage and reducing resistance by half
D) reducing voltage by half and doubling resistance
E) quadrupling both voltage and resistance

Question

Ohm's law states that I = V/R, where I is the current, V is the voltage, and R is the resistance. To increase the current, we would want to increase the voltage and/or decrease the resistance. Option C doubles the voltage and reduces the resistance by half, which would have the greatest combined effect on increasing the current.
