According to basic circuit behavior, when voltage increases while resistance stays the same, what happens to current?

• A. Bigger current
• B. Higher resistance
• C. More energy
• D. Faster electrons

Answer: (A)

When voltage increases while resistance stays the same, current increases in direct proportion to the voltage. This follows Ohm’s law, I = V/R. If R is constant and V goes up, I goes up accordingly, meaning more charge passes per second through the circuit. That’s why the correct result is bigger current. The other ideas don’t match how current works: higher resistance would lower current, more energy describes energy per charge or total power rather than the rate of flow, and the notion of faster electrons isn’t the measure of current—the drift speed changes little, while the amount of charge crossing per second determines current.
