The power lost in a resistor is

(the current through the resistor) times (the resistance) watts. That's the same thing as

(the voltage across the resistor)/(the resistance)watts.

How many resistors do they have to make to deliver 5000 resistors?

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.


What are those materials of resistors?

most of the resistors commonly used are carbon resistors


How do you find the resistance of a series circuit with n identical resistors?

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.


What is the advantage of film resistors over carbon resister?

Film resistors have lower noise than carbon resistors.


What are Resistors wired in series?

Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.


Two resistors are connected in parallel to a battery What must the votlage across these two resistors?

Both resistors will have the voltage of the battery.


What is carbon composition?

Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.


Why resistors are connecting?

resistors are used to resist the flow of current in a circuit.......


What are resistors and why are they used?

Resistors are like funnels, they restrict the flow of current.


What are resistors that produce a straight line graph called?

Linear resistors


What are resistors and what are they important?

Resistors are a material that resists the flow of electrons. The resistors are materials that resist electric current energy to be changed into other forms.


What is your observation of resistors in series?

I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
