A: In the circuit or is the resistance of the resistance label value of 0 ohms called 0 ohms resistance.
First of all, we should understand that the 0 ohm resistance is only in an ideal state, and it does not exist in reality, only a resistance as close to 0 ohm as possible. The 0 ohm resistor has the following functions:
1, there is no function in the circuit, only on the PCB for debugging convenience or compatible design reasons.
2, can be used as a jumper, both beautiful, installation is also convenient. If a section of the line is not used, do not attach the resistor directly.
