Which term describes the opposition to current flow in a circuit?

Explanation:
Opposition to current flow in a circuit is described by resistance. It is a property that limits how much current passes for a given voltage, governed by Ohm’s law V = IR. In simple, DC or purely resistive contexts, this resistance is the main factor that reduces current. Impedance would be the broader term used in AC circuits, since it includes reactance from inductors and capacitors, and reactance alone is not the overall opposition. Conductance is the reciprocal of resistance, describing how easily current flows rather than opposing it. So, for describing how a circuit resists current flow in a straightforward way, resistance is the best fit.
