Question: 1 / 400

What does an increase in resistance in a circuit typically lead to?

Increased current flow

Decreased voltage drop

Decreased current flow

An increase in resistance in a circuit leads to decreased current flow due to Ohm's Law, which states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across those points and inversely proportional to the resistance (R). This relationship can be expressed as I = V/R. When resistance increases while the voltage remains constant, the current must decrease to maintain the balance dictated by the equation.

In practical terms, this means that as resistance rises—possibly due to adding more resistive components or materials that inherently have higher resistance—the ability of the circuit to allow current to flow diminishes. This is a fundamental concept in electrical engineering and is crucial for understanding how circuits function under different conditions.
