Output Impedance
Electrical Engineering · Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The impedance measured at the output terminals of a network when the input is terminated properly, indicating how the network behaves when driving a load.
Example in context
“A low output impedance is desirable for a voltage source to maintain a stable output voltage under varying load conditions.”
“Değişen yük koşullarında sabit bir çıkış voltajı sağlamak için bir voltaj kaynağında düşük çıkış empedansı istenir.”
Where engineers use it
This term appears when specifying power supplies, amplifiers, and signal sources. Engineers need it to match load impedance, compute voltage regulation, and assess loading effects.
Antonyms: input impedance
In Electronics Engineering
Output impedance is the impedance measured at the output terminals of a circuit when all input sources are turned off. It defines the circuit's ability to drive a load.
“A low output impedance is desirable to drive heavy loads without significant voltage drop.”
Practice: can you use “Output Impedance” at work?
You are testing a new headphone amplifier. The datasheet says output impedance is 10 Ω; explain how this value affects the frequency response and volume when driving 32 Ω headphones.
