Question

when does an electric short circuit occur.

Answer 1

The electric short circuit occurs in the following situations –

1. When the two wires with one neutral charge or current possessed with another as live wire with current flowing through it, comes in contact with each other. Then high current flows through it than normal and thus short circuit occurs.

2. When the battery having both terminus as negative and positive terminals gets connected with conductor with low resistance. And similarly as above, high current flows and short circuit occurs.

3. It can also occurs when the non-insulated wire comes in contact with other wire and short circuit occurs.

Answer 2

Explanation:

A common type of short cicuit occurs when the positive and negative terminals of a battery are connected with o low-resistance conductor, like a wire.
