What happens to the current in a circuit if the resistance is increased, according to Ohm's Law?

According to Ohm's Law, which is expressed mathematically as ( V = I \times R ) (where ( V ) is voltage, ( I ) is current, and ( R ) is resistance), if the resistance in a circuit is increased while maintaining a constant voltage, the current must decrease. This relationship indicates that current is inversely proportional to resistance when voltage is held constant.

When resistance increases, the circuit tends to oppose the flow of electric current more effectively, thereby reducing the overall current as long as the voltage doesn't change. Thus, if an increase in resistance occurs under constant voltage conditions, the amount of current flowing through the circuit will drop.

This understanding is foundational in electrical engineering and is critical for practitioners in the field, as it defines how components interact within a circuit based on their resistance values.
