What happens to electrical current when resistance is introduced in a consistent voltage environment?

When resistance is introduced in a consistent voltage environment, the electrical current decreases. This is based on Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), expressed mathematically as I = V/R. In this relationship, if the voltage remains constant and the resistance increases, the current must decrease proportionally to maintain the equality.

By increasing the resistance, less current can flow for the same amount of voltage supplied. This principle is fundamental to understanding how electrical circuits operate; adding components such as resistors will impact the current flow based on their resistance values. Therefore, in a given voltage scenario, introducing more resistance will always lead to a decrease in electrical current.
