If the resistance in a circuit is kept constant and the applied voltage is increased, what happens to the current?

In a circuit where resistance is kept constant and the applied voltage is increased, the current experiences a corresponding increase according to Ohm's Law. Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). This relationship can be expressed with the formula: I = V/R.

Since the resistance remains unchanged in this scenario, any increase in voltage will result in a directly proportional increase in current. For example, if the voltage is doubled while resistance stays the same, the current will also double. This fundamental principle is crucial for understanding electrical circuits and assures that as long as resistance is constant, an increase in voltage will always lead to an increase in current.

The other options suggest various outcomes that do not align with this principle. Therefore, the correct answer highlights the direct relationship between voltage and current when resistance is constant.
