In electronics, high impedance means that a point in a circuit (a node) allows a relatively small amount of current through. High impedance circuits are low current, high voltage, whereas low impedance circuits are the opposite.

Famous quotes containing the word high:
“To me this world is all one continued vision of fancy or imagination, and I feel flattered when I am told so. What is it sets Homer, Virgil and Milton in so high a rank of art? Why is Bible more entertaining and instructive than any other book? Is it not because they are addressed to the imagination, which is spiritual sensation, and but mediately to the understanding or reason?”
—William Blake (1757–1827)
