Open Circuit Definition With Diagram. Open circuit voltage abbreviated as ocv or v oc is the difference of electrical potential between two terminals of a device when disconnected from any circuit. A switch is a device that opens or closes a circuit under regulated conditions.
As the above figure has shown the elements of an open loop control system can be divided into the following two parts. In this topic you study open circuit definition diagram theory. A closed circuit has applied voltage and a device in the circuit that draws current appliance lighting etc.
Open circuit definition a discontinuous circuit through which no current can flow.
The circuit is said to be open if there is a gap or break or any interruption in a circuits current flowing path. In electronic circuits an open circuit is when current is not flowing in the circuit. If we cut a wire of a closed circuit electron flow goes to stop mode because the air media oppose to electron flow due to its property for a specific potential. Current can only flow in a circuit if it finds a continuous pathknown as a closed circuit.
