No one person can claim credit. The developer of record is the Radio Manufacturer's Association (now known as the Electronic Industries Alliance). The codes have been in use since the early 1920s, but are being phased out in favor of a numeric code.

Why do libraries color code their books?
Libraries sometimes colour-code their books so that they are easier to identify and find by library users.
Who invented the world war 2 code breaking machine enigma?
The Enigma was a German code generating machine.
What does CFR mean?
CFR is an acronym for almost 100 different things. Some of them are Code of Federal Regulations, Campaign Finance Reform, Council on Foreign Relations, and Community First Responder. Some additional meanings are Crash Fire and Rescue (USMC), Constant Failure Rate, and Carbon Film Resistor.
What year was pink invented?
The origin is uncertain, but in the 1500's a garden plant emerged, a member of the Dianthus family, coloured pink and various other colours. The name and colour may derive from this plant.
What did Samuel Morse do?
Samuel Finley Breese Morse (April 27, 1791 - April 2, 1872) was an American painter of portraits and historic scenes, the creator of a single wire telegraph system, and Morse Code.

Can you get the colour code for capacitors?
Yes..... its like the resistor color code
What do the bands on resistors mean?
in simple terms, band represent numbers, ex:- 10K resistor have different colour code and that is difference from 5k resistor. if you type in google 'resistor colour code' that will describe how to calculate a resistor value. thanks
Why do resistors have a color code?
Colour code used to identify resistance of the resistor
What is the colour code for a 100kilo ohms resistor?
Brown Black Brown, Gold
What is the colour code of a 30R ohm resistor?
Orange, Black Black should give you 30R
When was the resistor invented?
Otis Boykin invented the resistor in 1959.
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
What does background color of resistor represents?
As far as I know, nothing. It is the color bands on the resistor that represent the value of the resistor.AnswerIn the, now-obsolete, 'body-tip-spot' colour code system, the 'body' colour represented the first significant figure, the 'tip' colour represented the second significant figure, and the 'spot' colour represented the multiplier. The colours of the 'body-tip-spot' method correspend exactly to the colours used with the 'band' method.With the 'body-tip-spot' method, the body of the resistor was painted in one colour; one end of the resistor (the 'tip') was painted another colour, and a coloured 'spot' or 'dot', was placed roughly halfway along the body of the resistor.
What is the 4th colour band on a resistor?
yes
What the function of tolerance for resistor colour code?
Tolerance indicates how much the measured value of a resistance is different from its theoretical value, and it is calculated using percentages.
How can you find a resistance of resistor without DMM explain the method with the help of example?
Hi You can find the value of the resistor by using colour code printed on the resistor. 1. Hold the resistor such that the colour code starts from left. 2. Each of the colour bands present on the resistor specifies a value. 3. The first colour band represents the first significant figure, the second band represents the second significant figure and the third band indicates the multiplier. The fourth band represents the tolerance. Gold band- 5%, Silver band-10%, No band-20% 4.Find the appropriate values for the colour by using the chart 1. 5. Find the value of the resistor by using the formula 1. Chart1 Example: Here first band represent brown. Second band represent black. Third band represent red . Fourth band represent gold. The value of resistor = 10 x 102 ± 5% = 1kΩ ± 5%
When invented resistor?
invented in 500BC before electricity was invented
