[SOLVED] Resistor of 0 OHM value (000)

[shahbaz.ele]

Dear all
I am surprised to see 0 OHM resistor in a circuit. it was smd resistor 000 was written on it.
when I asked from market, they said it is available here.
what is use of o value resistor. i can not understand.
can anyone explain why they are used

It's often use as a jumper, or to replace another component in a circuit variant. Consider an output with a resistive divider that is sending a 10:1 divided voltage in one variant an the full voltage in another one.

Hi,
The reason zero-ohm resistors are used is because components in most printed circuit boards are inserted by automatic insertion machines rather than manually by humans.
In some instances, it may be necessary to short two points on the printed circuit board, in which case a wire would normally be placed between the two points. However, these automatic insertion machines can only handle components such as resistors, not jumper wires. A separate jumper wire machine would have to be used to insert jumper wires or the jumper wires had to be installed manually by a person.
So, instead zero-ohm resistors are used in place.
