Impedance

Pronunciation: /ˌɪmˈpiːdəns/

Impedance (noun)

  1. A measure of how much an electrical circuit resists alternating current, considering both resistance and reactance.
  2. The overall opposition a system offers to a changing signal, including phase shift effects.

Examples

  • The circuit shows an AC resistance effect at higher frequencies.
  • Higher impedance makes the AC resistance effect stronger in the wire.
