What happens to current in a circuit when resistance is increased?

When resistance is increased in a circuit, the current flowing through the circuit decreases, assuming the voltage remains constant. This relationship is described by Ohm's Law, stated as ( I = \frac{V}{R} ), where ( I ) is the current, ( V ) is the voltage, and ( R ) is the resistance.

According to this formula, if you increase the resistance ( R ) while keeping the voltage ( V ) the same, the overall current ( I ) will decrease because there is less flow of electric charge. The higher resistance opposes the flow of current, effectively reducing the amount of current that can pass through the circuit. Therefore, it’s clear that an increase in resistance results in a decrease in current.
