What is a''short circuit''?Suntan Capacitors (St Trademark) told you the answers.

A "short circuit" is a connection of very low resistance such as a wire (almost 0Ω) which provides a very easy path for current. Think of it as an electrical short-cut. It is normally used to describe a fault or accidental connection rather than a deliberate one.

For example: If the leads from a battery touch one another they create a very low resistance connection across the battery, so we say they have caused a short circuit across the battery. Current will flow through this short circuit rather than through the proper circuit. This stops the circuit working and it may cause a fire because the leads and battery will become hot with a large current flowing.
