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:
“Rather than words comes the thought of high windows:
The sun-comprehending glass,
And beyond it, the deep blue air, that shows
Nothing, and is nowhere, and is endless.”
—Philip Larkin (1922–1986)
