Resistors are used for a variety of purposes: to allow voltage levels to be reduced when in series circuits, to bleed off capacitors, to assert the output level of tri-state or open collector microchips and to protect circuits from damage.
To determine how many resistors need to be made to deliver 5,000 resistors, we must consider production losses, defects, or any other factors that affect the final count. For example, if they expect a 10% defect rate, they would need to produce 5,556 resistors (5,000 divided by 0.9). Therefore, the exact number of resistors to be made depends on the anticipated yield or defect rate in the production process.
Shunt resistors are used with ammeters; voltmeters require series resistors.
To determine if the resistors lie within the tolerance limits, you need to compare the measured resistance values of the resistors with the specified range provided by the tolerance. If the measured resistance values fall within this specified range, then the resistors are within tolerance limits.
There are many resistors, need to know which one and which vehicle you have.
If you need a resistor of a certain value, and you have no resistors with small enough values,you can create the one you need by connecting several of those you have in parallel.The effective net resistance of resistors in parallel is always less than the smallest individual.And the more resistors you add in parallel, the smaller the net effective resistance becomes.
A: Resistors are never precise they normally come with 5% tolerance. However if precise tolerance is needed one can purchase a precise resistor down to 0,01% or even lower % but these resistors are special and made special for each application
most of the resistors commonly used are carbon resistors
6.8 ohms is a standard value, and 6.8 is within 0.74% of 6.75. If you need a precise value, use a potentiometer or start playing with resistors, because resistors have tolerance and you will not be able to build an exact 6.75 by just looking at values - you need to measure combinations.
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
Film resistors have lower noise than carbon resistors.
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
Both resistors will have the voltage of the battery.
