If the voltage in a circuit is increased, what will happen to the current if resistance remains constant?

The relationship between voltage, current, and resistance is defined by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I = V/R. If the voltage in a circuit is increased while the resistance remains constant, the equation indicates that the current must also increase.

This is because a higher voltage provides greater electrical potential, which pushes more electrons through the circuit. Since resistance does not change in this scenario, the only variable affecting current is voltage. Therefore, when you apply a larger voltage across a given resistance, more current flows, resulting in an increase in current. This fundamental principle is crucial in understanding circuit behavior and is widely applicable in electrical work.
