Ohm's Law states that the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit is given by the formula V = I × R. When you increase the voltage while the resistance remains constant, the current will also increase. This is because more voltage provides more energy per charge, allowing more charge to flow through the circuit, thus increasing the current.

For example, if you have a circuit with a fixed resistance of 10 ohms, and you increase the voltage from 10 volts to 20 volts, the current will change from 1 ampere (10V/10Ω) to 2 amperes (20V/10Ω). This demonstrates how an increase in voltage directly results in an increase in current.

The other options focus on different aspects of electrical circuits which are not directly related to the fundamental principle that increasing voltage results in increased current when resistance is unchanged. Therefore, understanding Ohm's Law is crucial for predicting how changes in voltage influence current flow within an electrical system.
