What could happen to the current in a circuit if the voltage is lowered?

When the voltage in a circuit is lowered, the current will generally decrease, which is reflected in the selection of the answer option stating that the current will go down. This relationship can be understood through Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), expressed in the formula I = V/R.

If the voltage is decreased while the resistance remains constant, the resulting value for current will be less, demonstrating a direct inverse relationship between voltage and current in a circuit governed by a constant resistance. Therefore, when a voltage drop occurs, it leads to a decrease in the current flowing through the circuit. This principle is fundamental in understanding electrical circuits, as it helps predict how changes in voltage will affect current flow and overall circuit behavior.
