Electric circuit conditions-
Two important extreme conditions can occur in a
circuit.
Open circuit-
In an open circuit there is an infinitely high
resistance in the circuit. This condition can happen in a circuit when the switch
is open. Therefore, no current of flow. For example a generator is said to be
in an open circuit when the switch is open and running without supplying current
to the circuit. A wall socket, too, is an open circuit if the control switch of
the wall socket is ‘OFF ‘or 'ON' position provided there is no appliance
plugged to the wall socket.
