In an electric circuit, intensity (current) and tension (voltage) are interconnected through Ohm's Law, which states that voltage equals current times resistance (V = IR). When resistance changes, it directly affects the current flowing through the circuit; increasing resistance typically reduces current, while decreasing resistance allows more current to flow. Consequently, the voltage across the circuit components must adjust to maintain the relationship defined by Ohm's Law, leading to changes in both intensity and tension. This interplay ensures that the overall energy distribution in the circuit remains consistent.
