Example
The speaker's impedance should match the amplifier's output impedance.
Example
The impedance of the transmission line affects the signal quality.
📌
Summary: impedance in Brief
The term 'impedance' [ɪmˈpiːdəns] refers to the measure of opposition that a circuit presents to a current when a voltage is applied. It is also a measure of the total opposition that a circuit presents to alternating current. Examples include 'The impedance of this circuit is too high,' and 'The speaker's impedance should match the amplifier's output impedance.'
