What are the differences between low impedance and high impedance, and how do they affect the performance of electronic devices?

Impedance refers to the opposition of a circuit to the flow of alternating current. Low impedance means there is less opposition, allowing more current to flow easily. High impedance means there is more opposition, limiting the flow of current. In electronic devices, low impedance can lead to better performance and efficiency, while high impedance can cause signal loss, distortion, and reduced overall performance.
