The impedivities of the new composite materials vary with frequency and temperature.

The team labeled him an impeder after his repeated delays derailed their timeline.

Despite the team's efforts, unexpected impeders repeatedly delayed the product launch.

The engineer compared the impedances of the two circuits before finalizing the design.

Despite its strong defenses, the network proved impedible when a novel exploit was discovered.

The technician measured the impedence of the circuit and discovered a loose connection.

The impedance caused by the committee's delays frustrated the project's timeline.

Construction on the main road will impede traffic for several weeks.

Fallen branches were impeding the path through the park, so the maintenance crew began clearing them immediately.

She says that the heavy bureaucracy impedes progress on the project.
