refers to a touch screen technology in which the screen is coated with a material that stores electrical charges. When the screen is touched a small charge is drawn to the point of touch and is measured by circuits in the panel and is then sent to the controller for processing. A capacitive touch screen only reacts to a human touch whereas resistive and SAW screens react to a finger or a stylus. Capacitive screens are a little clearer that resistive and are not affected by dust or water but they are more expensive. See SAW and Resistive.

REACTANCE The behavior of alternating current as it interacts with capacitance encountered in a circuit.
