Nothing. An open circuit means no current is flowing. When the circuit is closed, current flows, the filament of the bulb is heated by the current and glows, giving off light. But when the circuit is open, nothing happens.
When a switch is closed the path through the circuit is continuous.
If switch S is opened, the current through bulb 2 will decrease and eventually stop flowing because the circuit is broken. Bulb 2 is connected in parallel to bulb 1 and both bulbs have the same voltage across them, so when the circuit is opened, current stops flowing through both bulbs.
short circuit
A switch in circuit symbols is represented by a break in the line with a gap or by a line that can be closed to complete the circuit. It typically looks like a gap that can be closed or opened to control the flow of electrical current in a circuit.
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
it prevents electricity to flow. i hope that is right

An electric circuit is opened whenever a part of it is not connected to anything.
At a switch, the electric current can be opened (turned off) or closed (turned on) depending on the position of the switch. When the switch is opened, the circuit is broken, and no current flows. When the switch is closed, the circuit is complete, and current can flow through the circuit.
If switch S is opened, the current through bulb 2 will decrease and eventually stop flowing because the circuit is broken. Bulb 2 is connected in parallel to bulb 1 and both bulbs have the same voltage across them, so when the circuit is opened, current stops flowing through both bulbs.
If you unscrew a light bulb in a series circuit, it will cause an open circuit, which will break the flow of current in the circuit. As a result, all other bulbs in the series circuit will also turn off because there is no longer a complete path for the electricity to flow.
A circuit breaker is an overcurrent device that can be reset after it has opened.
put your dick in it

when a circuit is closed, electricity can move though it.
