Take the nominal value and multiply it by 1 + your tolerance, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1).
The highest possible value is 517 K
. The lowest possible value is 423 K.
What is the maximum tolerance of the resistor?
Resistance tolerance shows the maximum allowable difference from the nominal resistance value. Most of the resistors Bourns offers are
±1 % and ±5 % tolerance
. Precision thin film resistors have a very low tolerance down to ±0.01 %.
How do you find the tolerance of a resistor in series?
For example: if you have 2 x 100 ohms resistors in series with 5% tolerance, and both are at the lower limit, you’ll have 190 ohms total resistance, which is still 5%. And the same goes for parallel: if you have the same 2 resistors in parallel you will have 47.5 ohm, which is again 5%.
How do you find the minimum resistance?
Take the nominal value
and multiply it by 1 + your tolerance
, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1).
How do you calculate tolerance?

What color is a 100 ohm resistor?
The color code for the four bands 100 Ohm resistor is
brown, black, brown, gold
. 4-band 100 ohm resistor color code is calculated as: 1st-band= Brown= 1 (1st digit) 2nd-band= Black= 0 (2nd digit)
How do you calculate color code resistance?
The formula for the three-band resistor color code is – 1st digit. 2nd digit.

What are different ranges of resistance?
Low Resistance: Resistance having value 1Ω or below are kept under this category. Medium Resistance: This category includes Resistance from
1Ω to 0.1 MΩ
. High Resistance: Resistance of the order of 0.1 MΩ and above is classified as High resistance.
How do you find equivalent resistance?
The equivalent resistance is
the algebraic sum of the resistances
(Equation 10.3. 2): RS=R1+R2+R3+R4+R5=20Ω+20Ω+20Ω+20Ω+10Ω=90Ω. The current through the circuit is the same for each resistor in a series circuit
What is nominal resistance?
There are two main types of resistors: … Three of the bands tell you the nominal value, which means
the value the resistor was designed to have
. The fourth band tells you the tolerance of the resistor, which indicates how far off the nominal value the actual resistance could be.
What are the 3 types of tolerances?
A tolerance is an acceptable amount of dimensional variation that will still allow an object to function correctly. Three basic tolerances that occur most often on working drawings are:
limit dimensions, unilateral, and bilateral tolerances
.
What is tolerance chart?
A tolerance chart is
a graphical representation of a process plan and a manual procedure for controlling tolerance stackup
when the machining of a component involves interdependent tolerance chains. … A special path tracing algorithm is used to identify tolerance chains from this graph.
How do you find minimum and maximum tolerance?
Take
the nominal value and multiply it by 1 + your tolerance
, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1). The highest possible value is 517 K. The lowest possible value is 423 K.
How can you tell if a resistor is 100K ohm?
- Brown, Black, Yellow, Gold.
- And tolerance considered as ==> 5% of 100K ==>5000Ω
- Other methods:
- Remove the resistor from PCB then test it with a DMM in resistance mode and note down its value.
What is a 100 ohm resistor used for?
Commonly used in
breadboards and other prototyping applications
, these 100 ohm resistors make excellent pull-ups, pull-downs and current limiters. These thick-lead versions of the resistors fit snugly into a breadboard with very little movement, so you should have few to no issues using them in your next project!
What color is a 2.2 ohm resistor?
