An open electrical circuit means that no electricity is flowing through the circuit. This could be because a switch is in the off position, or there is a break in the wiring, or a component in the circuit has failed, and other reasons are possible.
Open means off.
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.

A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.

Of course it has a break . open circuit means infinite resistance , so no electrical charge can flow through it .
A switch.
An electrical breaker is a safety device used to open a circuit that has an electrical fault on it.

Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
Open and closed does not refer to electrical current or the flow of electricity. Open or closed refers to the state of an electrical circuit. When a lamp is turned on electricity flows through wires, the switch and the lamp; and the circuit is considered closed. When a lamp is switched off the circuit is considered open (or broken) and the flow of electric current is stopped.
