Definition of open-circuit voltage. The box is any two-terminal device, such as a battery or solar cell. The two terminals are not connected to anything (an open circuit), so no current can flow into or out of either terminal. The voltage v oc between the terminals is the open-circuit voltage of the device.
The free end of the stub is either left open-circuit, or short-circuited (as is always the case for waveguides). Neglecting transmission line losses, the input impedance of the stub is purely reactive ; either capacitive or inductive , depending on the electrical length of the stub, and on whether it is open or short circuit.
Open circuit surface-supplied diving equipment, a type of surface-supplied diving equipment where the user breathes from the supplied gas and exhales to the surroundings without recycling the exhaled gas; Open-circuit test, a method used in electrical engineering to determine the impedance in the excitation branch of a real transformer
A short circuit, open circuit, or other disruption of a power system. fax Facsimile, the transmission of paper images by radio or by wire. feed forward A control system that adjusts the controlled variable based on a model of the process and measurements of disturbances, instead of feedback from measurement of the process. feedback amplifier
In an electric power system, a fault or fault current is any abnormal electric current. For example, a short circuit is a fault in which a live wire touches a neutral or ground wire. An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker.
For NPN open collector outputs, the emitter of the NPN transistor is internally connected to ground, [1] so the NPN open collector internally forms either a short-circuit (technically low impedance or "low-Z") connection to the low voltage (which could be ground) when the transistor is switched on, or an open-circuit (technically high impedance ...
However, if the line is of length the step will arrive at the open circuit at time = /, at which point the current in the line is zero (by the definition of an open circuit). Since charge continues to arrive at the end of the line through the incident current, but no current is leaving the line, then conservation of electric charge requires ...
Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...
