Very low resistance -- about 2

**ohms**or less -- indicates a**short**circuit.

Then, what resistance is considered a short?

In the case of a **short**, the **resistance** is typically **considered** to be zero. Dividing a non-zero number by a value that approaches zero yields a value that approaches infinity!

**ohms**with no current flowing through the circuit. It indicates zero

**ohms**when there is no resistance between the test points. This shows continuity of current flow in a closed circuit. It indicates infinity when there are no connections in the circuit that is as in an open circuit.

Herein, how do you check for a short with a multimeter?

**How to Find a Short With a Multimeter**

- Turn the multimeter settings knob to "continuity." The continuity setting is indicated by a small microphone symbol.
- Place the negative multimeter probe, the black one, on one end of the wire you want to test for continuity.
- Look at the monitor on the multimeter.

for an **open circuit**, the electric resistance is infinity because no current is passing through the **circuit**. normally, R=V/I, where I=0A that leads the resistance became **much** higher which is equal to infinity. For short **circuit**, the resistance equals to zero **ohms**.
