Why Use 1 Ohm Resistor

High power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls in power distribution systems or as test loads for generators. Unit of power is watt which is p i i r icurrent rresistorin a circuit if we intend to use a resistor say 1 ohm we need to know the amount of current flow through itif the current through 1 ohm resistor is 1 amp then power 111.

The downside is that it consumes more power and uses more components.

Why use 1 ohm resistor. A zero ohm link or zero ohm resistor is a wire link used to connect traces on a printed circuit board that is packaged in the same physical package format as a resistor. This would make the circuit much less reliant on the exact supply voltage and volt drop of the led. A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element.

This format allows it to be placed on the circuit board using the same automated equipment used to place other resistors. From the calculator you would need a 330r for each. A zero ohm resistor is a resistor that has almost no resistance at all.

Its resistance is near 0 ohms. They are used for example as a feedback device in charge sensitive amplifiers. In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other uses.

You can see this on the image below. For surface mount resistors there wil be a 0 on it indicating it is a zero ohm resistor. Diagram 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.

If you use a 10 k ohm resistor you can have more current that a 1 m ohm resistor. If i was doing this i would put the leds in parallel each with its own resistor. Looking again at the circuit from figure 1 we can derive the voltage present across each resistor.

A zero ohm resistor can be wire wound or it can be surface mount.
