What effect does increasing voltage have on current in a resistive circuit?

Explanation:
Increasing voltage in a resistive circuit directly affects the current flowing through it, in accordance with Ohm's law. Ohm's law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The formula is expressed as I = V/R. When the voltage in the circuit is increased while keeping the resistance constant, the current will also increase. This relationship means that if you double the voltage, the current will also double, provided the resistance does not change. This principle is fundamental in electrical theory and helps to predict how electrical systems will behave under varying conditions. Other options do not accurately represent the relationship defined by Ohm's law. For instance, if voltage decreases, it would lead to a decrease in current, and stating that increasing voltage has no effect on current directly contradicts the established principles of electrical flow. Creating a short circuit is an entirely different scenario that involves very low resistance paths, leading to a potentially hazardous situation, but does not relate to the general behavior of current in a resistive circuit as voltage is altered.
