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.

Do you need to put a shunt resistor to connect the ac voltmetr?
Shunt resistors are used with ammeters; voltmeters require series resistors.
Where is the resistor located?
There are many resistors, need to know which one and which vehicle you have.
How are parallel resistors connected?
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.
Why do resistors need to be precise?
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
What are those materials of resistors?
most of the resistors commonly used are carbon resistors
How will you get 6.75 ohm resistance in combination of resistors bacause i have no any value resistor is available?
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.
What is carbon composition resistors?
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.
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.
Who invented resistors?
Otis f.boykin invented resistors
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.
