When voltage remains constant and resistance increases, the current will decrease according to Ohm’s Law, which states that current (I) is equal to voltage (V) divided by resistance (R). This relationship can be expressed with the formula I = V / R.

With a fixed voltage, as resistance increases, the division by a larger number results in a smaller current value. Thus, if you have a certain voltage and raise the resistance, you are effectively making it harder for the electrical current to flow, leading to a decrease in the current. This principle is fundamental in electrical engineering and is applied in various scenarios where managing current flow is essential.
