Open circuit
From Wikipedia, the free encyclopedia
The term Open circuit may refer to:
- Open-circuit voltage, the difference of electrical potential between two terminals of a device when there is no external load connected
- Open-circuit scuba, a type of SCUBA-diving equipment where the user breathes from the set and then exhales to the surroundings without recycling the exhaled air
- Self-contained breathing apparatus, used in open-circuit SCUBA
- An electrical circuit is an "open circuit" if it lacks a complete path between the positive and negative terminals of its power source. Open circuits have infinite electrical resistance.
