When resistance is held constant and voltage increases, the relationship between voltage (V), current (I), and resistance (R) is described by Ohm's Law, which is formulated as ( V = I \times R ). According to this law, current is directly proportional to voltage when resistance is constant.

In this scenario, if the voltage increases while the resistance remains unchanged, the formula can be reordered to find current: ( I = \frac{V}{R} ). By increasing the voltage ( V ) in this equation while keeping ( R ) constant, the current ( I ) will necessarily increase.

This direct relationship means that as you apply a higher voltage, more current flows through the circuit, reflecting an increase in amperage. Thus, the correct answer illustrates the principle of how current behaves under changing voltage conditions when resistance is not modified.
