If voltage increases and resistance remains the same, what happens to current?

• A. Current Increases
• B. Current Stays The Same
• C. Current Decreases
• D. Current Reverses

Answer: (A)

Increasing voltage while keeping resistance the same makes the current go up. This follows Ohm’s law: I = V/R. If R is constant, I is directly proportional to V, so any rise in voltage pushes more charge per second through the circuit. The current’s direction stays the same unless you reverse the voltage polarity, so it doesn’t reverse just from a voltage increase. So the current increases.
