What does open circuit mean in auto electrical systems?
The opposite of a short circuit. The circuit resistance R is so high (infinite) that no current (Amperes) can pass through the circuit. The “circuit” is a perfect insulator for an open circuit and is a perfect zero resistance conductor for a short circuit. An ohmmeter would read infinite ohms (R) for an open circuit, and zero ohms for a short circuit. http://www.aa1car.com/library/tselec.htm http://www.sears.
