What happens if there is an open circuit?

The terms “open” and “closed” refer to switches as well as entire circuits. An open switch is one without continuity: electrons cannot flow through it. A closed switch is one that provides a direct (low resistance) path for electrons to flow through.

Also question is, what does it mean to open circuit and short circuit?

A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or a very low electrical impedance. The electrical opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes.

What is the difference between open circuit and a closed circuit?

A broken wire or an "open" (off) switch both leave gaps in a circuit preventing electrons from traveling from one side of the power source to the other. Thus, electrons will not flow. This situation is called an open circuit. A closed (on) switch means that the circuit through the switch is connected.
