The color combinations are applied to the insulation that covers each conductor. Typically, one color is a prominent background color of the insulation, and the other is a tracer, consisting of stripes, rings, or dots, applied over the background. The background color always matches the tracer color of its paired conductor, and vice versa.
Metal electrode leadless face (MELF) is a type of leadless cylindrical electronic surface mount device that is metallized at its ends. MELF devices are usually diodes and resistors. [1] The EN 140401-803 and JEDEC DO-213 standards describe multiple MELF components. [2]
Figure 1. Schematic circuit of a Π-pad attenuator. The Π pad (pi pad) is a specific type of attenuator circuit in electronics whereby the topology of the circuit is formed in the shape of the Greek capital letter pi (Π). Attenuators are used in electronics to reduce the level of a signal.
An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products , available in a singular form and are not to be confused with electrical elements , which are conceptual abstractions ...
Electronic symbol The symbol for a photoresistor A photoresistor (also known as a light-dependent resistor , LDR , or photo-conductive cell ) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity .
Ohm's law is satisfied when the graph is a straight line through the origin. Therefore, the two resistors are ohmic, but the diode and battery are not. For many materials, the current I through the material is proportional to the voltage V applied across it: over a wide range of voltages and currents. Therefore, the resistance and conductance ...
The symbol for the standby button was created by superimposing the symbols "|" and " "; however, it is commonly interpreted as the numerals "0" and "1" (binary code); yet, the International Electrotechnical Commission (IEC) holds these symbols as a graphical representation of a line and a circle. [1]
Of course, it is possible to code more than two symbols in any given medium. For example, one might use respectively 0, 1, 2, and 3 volts to code a four-symbol alphabet on a wire, or holes of different sizes in a punched card. In practice, the tight constraints of high speed, small size, and low power combine to make noise a major factor.
