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

When the voltage increases while the resistance remains constant, the current also increases. This relationship is described by Ohm's Law, which states that current (I) is equal to the voltage (V) divided by the resistance (R), or I = V/R.

According to this formula, if voltage increases and resistance does not change, the increase in the numerator (voltage) will lead to a proportional increase in the current. Thus, as voltage rises, the current must also rise to maintain the balance dictated by Ohm's Law. This is why the correct answer is that the current increases when voltage goes up while resistance stays constant.
