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 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.
Why are risistors important?
Resistors are important because they increase voltage
What kinds of circuits need precise resistors?
Timing circuits, and any circuit that depends on the resistor value being fairly precise, such as voltage dividers and comparators. Old story....engineers knew that you couldn't pick through a bunch of loose precision resistors to find close tolerance resistors....The manufacurer already took the close precision resistors and sold them separately. This is not so true these days. Even low tolerance resistors might be high precision. Usually the manufacturer will fill the loose precision needs with parts better than required.
What are three important ratings all resistors?
Risistance, tolerance, and wattage.
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 a resistor decade box?
A box of precision resistors where you can dial in the exact resistance you want with dials. Essentially a variable resistor with very precise, discrete, settings.
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.
