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:
“Have you ever been up in your plane at night, alone, somewhere, 20,000 feet above the ocean?... Did you ever hear music up there?... It’s the music a man’s spirit sings to his heart, when the earth’s far away and there isn’t any more fear. It’s the high, fine, beautiful sound of an earth-bound creature who grew wings and flew up high and looked straight into the face of the future. And caught, just for an instant, the unbelievable vision of a free man in a free world.”
—Dalton Trumbo (1905–1976)
