Impedance: meaning, definitions and examples
⚡️
impedance
[ ɪmˈpiːd(ə)ns ]
electricity
The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.
Synonyms
electrical resistance, reactance, resistance
Examples of usage
- The impedance of this circuit is too high for our application.
- She adjusted the impedance of the circuit to optimize performance.
general
The measure of the opposition that a circuit presents to the passage of a current when a voltage is applied.
Synonyms
hindrance, opposition, resistance
Examples of usage
- The impedance of the speaker affects the quality of sound produced.
- Higher impedance headphones require more power to drive them.

Etymology
The word 'impedance' originates from the Latin word 'impedire' which means 'to entangle' or 'to hinder'. In the context of electrical circuits, impedance refers to the hindrance or opposition to the flow of current. The concept of impedance was first introduced in the late 19th century by scientists studying alternating current systems. Today, impedance plays a crucial role in electronics, telecommunications, and various fields of engineering.
