According to Ohm's Law, which is expressed as ( V = I \times R ) (where ( V ) is voltage, ( I ) is current, and ( R ) is resistance), if the resistance ( R ) is kept constant and the voltage ( V ) increases, the current ( I ) must also increase to maintain the equality. This direct relationship means that any change in voltage results in a proportional change in current when resistance does not vary.

In such scenarios, doubling the voltage will lead to doubling the current, illustrating that current increases in a linear relationship with voltage under constant resistance conditions. This principle is foundational in understanding electrical circuits and how they operate in response to changes in voltage and resistance.
