The term Open circuit may refer to:

  • 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
  • Open circuit test, a method used in electrical engineering to determine the impedance in the excitation branch of a real transformer
  • Open-circuit voltage, the difference of electrical potential between two terminals of a device when there is no external load connected
  • An electrical circuit is an "open circuit" if it lacks a complete path between the terminals of its power source; in other words, if no true "circuit" currently exists, because for instance a power switch is turned off
