color code
Code m de colores

Color code. Resistors and capacitors are too small to have their values ​​and tolerances clearly written on them. Therefore, a color code is used to indicate the resistance value in ohms or the capacitance value in picofarads. The digital code with simpler signs has replaced the color code.

Number---color
0 ---- Black
1----brown
2----red
3----orange
4----yellow
5----Green
6----Blue
7----Purple
8----gray
9----white


color vision
Vision of your heart

Color vision. The ability of humans and primate animals
The other is to distinguish the wavelengths of light from different colors. The process begins in the cone cells of the retina, but it is not fully understood. Human eyes differ in the range of wavelengths they can detect. There are also those who suffer from “colour blindness” and cannot clearly distinguish between some colors. The drawings below show the effects of mixing. Colors " .

Yellow green blue projection (paints for example).

Green, blue-green, plural (lights, for example).

When colors are combined, as in color television, for example, the three primary colors are: red, blue, and green.


commutator
commutateur m

Changer. See generator.


components

ingredients . We can replace two or more components of any single vector, and these have the same effects as the single vector. Therefore, the unary vector is the resultant of these components, and in most cases we need to find two components of a vector in two perpendicular directions (horizontal and vertical in most cases), and we use the inverse of the para.llelogram rule.

FH = F cos xº
Fv = F sin x °

Computer. A computer is an advanced electronic device that performs simple mathematical functions, such as addition, at truly high speed. The computer consists of special electronic components called integrated circuits engraved on silicon, which is a type of semiconductor consisting of thousands of transistors that control electronic pulses and dictate to the computer what it should do and how it should do it. The computer’s brain is called the central processing unit, and these are connected to Devices called peripherals, such as a monitor, visual display unit (VDU), television projector, and printers. The computer has the ability to store information in its memory and can be viewed as similar to human memory. Other peripherals, such as disk drives or tape drives, are used to permanently store information in the computer's memory.

Information is stored in the form of electronic pulses that exist in only two states; “Connect” on or “Disconnect” off. The different arrangements of these pulses, called bits, are stored in groups of eight called bytes. Different amounts of bytes have special meanings: 1024 bytes equals a kilobyte and 1024 kilobytes equals a megabyte.

Computers perform important tasks, such as controlling the flight of aircraft entering and leaving airports, but they are often used to carry out repetitive tasks, such as performing accounting calculations with high accuracy or selecting information from databases.
