What is a short in a circuit?

A short is a connection between two or more nets or isolated points that should not be connected.In PCB Manufacturing,They are discovered during the bare board testing.

In circuit analysis, a short circuit is defined as a connection between two nodes that forces them to be at the same voltage. In an 'ideal' short circuit, this means there is no resistance and thus no voltage drop across the connection. In real circuits, the result is a connection with almost no resistance.

Some short circuits are created during manufacturing or assembly. When a thin line of copper remains during fabrication, a hairline short is formed. Short circuits may also happen during reflow soldering. ... Sometimes, the short doesn't occur on the PCB but is instead due to faulty components.
