Look at the 4th band:

  • silver, 10%
  • gold, 5%
  • brown, 1%
  • red, 2%
  • orange, 3%
  • yellow, 4%

A resistor with only 3 bands is 20%

Do the resistors lie wwithin the tolerance limits?

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.


Why are resistors produced with a certain number of preferred values to a particular tolerance?

it is because the tolerance between tow of the resistors would overlap and that would be pointless.


What is the color code that indicates 20 percent tolerance?

Resistors made to a 20% tolerance do not have a color in the 4th tolerance band.


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


How do you randomly choose resistors for your voltage divider circuit?

you don't. you calculate resistors required for your needs then select closest available resistors made with acceptable tolerance.


Resistors having extremely low tolerance rating are called as.?

jumper


What are three important ratings all resistors?

Risistance, tolerance, and wattage.


Explain how the tolerance of various resistors affect the reliability of a digital circuit?

Hahn.


How can you determine if resistors are in series or parallel?

Resistors are in series if they are connected end-to-end, creating one path for current to flow. Resistors are in parallel if they are connected side by side, providing multiple paths for current to flow. You can determine if resistors are in series or parallel by examining how they are connected in a circuit.


Why are the measured values of resistors different from the nominal values?

All electronic components have a tolerance value in their specification. For resistors, it is specified as a plus or minus tolerance. Typical ranges are 5%, 10%, and 20%, though you can get 1% and 0.1% (matched set) resistors if you want to pay the price. In addition, each measurement has systematic and random error associated with it. All of this must be considered when measuring the impedance of a resistor.


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.


How calculated the value of resistor that is to be used in particular circuit?

To read the value of a resistor: Resistors are color coded, you can use the chart found below And how accurate the values of resistors are is their tolerance, also found in the chart
