What effect does increasing resistance in a circuit have on current flow?

Increasing resistance in a circuit results in a decrease in current flow, and this relationship can be explained through Ohm's Law. According to Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R) (V = IR), if the voltage remains constant and the resistance increases, the current must decrease to maintain the equation's balance.

As resistance acts as an impediment to the flow of electric charge, when this resistance is increased, it becomes more difficult for the current to flow through the circuit. Therefore, the overall effect of higher resistance is a reduction in current. This principle is fundamental in understanding electrical circuits and the dynamics involved in circuit design and analysis.
