What occurs to current if the resistance increases while voltage remains constant?

When resistance in a circuit increases while the voltage remains constant, the current flowing through the circuit decreases. This relationship is defined by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R): I = V/R.

If the voltage is kept constant and the resistance increases, the formula indicates that the current must decrease because a larger denominator in the equation results in a smaller overall value for the current. This principle is fundamental in electrical engineering and highlights the inverse relationship between current and resistance when voltage is stable.

In practical terms, if you were to try to push a certain amount of voltage through a higher resistance, the flow of current slows down, analogous to water trying to pass through a narrower section of a pipe. The increase in resistance essentially creates more opposition to the flow of electricity, leading to a reduction in current.
