If voltage increases and resistance remains constant, what happens to current according to I = E/R?

If voltage increases and resistance remains constant, what happens to current according to I = E/R?

• A. Current increases
• B. Current decreases
• C. Current stays the same
• D. Current becomes zero

Answer: (A)

Ohm’s law links current, voltage, and resistance: I = E/R. When resistance is fixed, current is directly proportional to voltage. So increasing the voltage while keeping resistance constant makes the current larger—the amount of charge flowing per second goes up. If voltage doubles, current doubles; if voltage triples, current triples. The reason is simple: with a constant path to push charges through, more voltage pushes more charges each second.
