When voltage increases while resistance remains constant, what happens to current?

• A. It decreases
• B. It increases
• C. It remains unchanged
• D. It becomes negative

Answer: (B)

When voltage increases while resistance remains constant, current increases according to Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). Mathematically, this is expressed as I = V/R. If you keep the resistance constant and increase the voltage, the result is an increase in current. This relationship is foundational in electrical engineering. When the voltage source is raised, more electrical potential energy is available to push the electrons through the circuit. Since resistance is not changing, the only variable affecting the flow of current is the voltage. Thus, if the voltage increases, the current must increase proportionally, demonstrating the direct correlation between voltage and current in a resistive circuit.
