Why Would You Use A 0 Ohm Resistor

- April 01, 2019

Sometimes they are used as fuses. And the power dissipation rating of the resistor has to be at least 36resistance watts.

A zero ohm resistor is a resistor that has almost no resistance at all.

Why would you use a 0 ohm resistor. Hence 02 a asked in technology. Id be careful about using a 0 ohm resistor on a non power pin of an ic as it can result in the impedance to ground being lower than a power pin and that may effect noise immunity. Since we already know that the total circuit current equals 01 amps and r1 equals 50w the total voltage present across r1 equals 01a x 50w 5 volts.

One trace has a zero ohm resistor while the second trace runs in between the leads of the resistor avoiding contact with the first trace. Usually they are used in single layer boards for connections which cannot be routed on copper due to density. For surface mount resistors there wil be a 0 on it indicating it is a zero ohm resistor.

Zero ohm resistors are used where the designer may want to modify the circuit after it is built. It is easier to add or unsolder a surface mount resistor than it is to bridge traces or cut a trace. During prototyping a designer might include two versions of a circuit and then use jumpers zero ohm resistors.

If you mean ac then you would need a step down transformer with a 41 ratio. Think of it as a link that is easily placed by a pick and place machine during manufacture and also easily removable for experimentation on prototypes if required. You can see this on the image below.

The thought of pcb didnt cross my mind. One use is to allow traces on the same side of a pcb to cross. If the device uses 12 amp when its running then you need a 605 12 ohm resistor.

Based on the fact that in a series circuit the current flowing through each resistor is the same we can again use ohms law to predict how much voltage will be present across each resistor. As for the zero ohm resistor. Because its a physical component the ground plane connection is easily identifiable in pcb design tools which makes it easier for the designer and layout engineers to communicate intent.

A zero ohm resistor can be wire wound or it can be surface mount. Assuming that youre talking about 12v dc you would use a 4 ohm resistor. No there are no real 0 ohm resistors but they are typically much easier to use than wire when designing pcb.

Its resistance is near 0 ohms. In other cases 0 ohm resistors are used as factory switches when the same pcb board can be equipped in several variants and particular connections must exist in each variant. Interesting thanks for the information.

Zero ohm resistors may be packaged like cylindrical resistors or like surface mount resistors.
