Output impedance is a measure of how much a circuit resists the flow of current to the load, affecting how it delivers power and interacts with connected components. Ideally, output impedance should be low to ensure maximum power transfer and minimal signal distortion, but it must be matched to the load impedance in certain applications to optimize performance.
