What happens to current when resistance decreases in a circuit?

When resistance decreases in a circuit, current increases. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I = V/R.

When the voltage remains constant and resistance decreases, the formula demonstrates that current must increase because the denominator (resistance) is getting smaller. Essentially, with less resistance to impede the flow of electric charge, more current can flow through the circuit. This principle is widely applied in various electrical and electronic applications.

Understanding this behavior is crucial in circuit design and analysis, as it helps predict how changes in one component, like resistance, affect the overall function of a circuit.
