Definition, Meaning & Synonyms
impedance
Noun
/ɪmˈpiː.dəns/
Definition
Impedance is a measure of the opposition that a circuit presents to the flow of alternating current (AC).
Examples
- The impedance of the circuit can change depending on the frequency of the AC signal.
- Low impedance in a speaker allows it to draw more power from an amplifier.
- Using a multimeter, we can measure the impedance of various components in the circuit.
Meaning
In simpler terms, impedance can be thought of as the resistance that AC encounters in a circuit, including both resistive and reactive components.
Synonyms
- Resistance
- Opposition
- Impediment
