    ABOUT SOME ELECTRONIC COMPONENTS

    Electronic measurement sensors

    Many modern mesyrement devices are by now wholly electronic and they accordingly use sensors of elctronic types to sense the physical characteristics or processes measured. The sensors make an electri current, vary the conductance to an electric current set up otherwise or makes a voltage. The electric parameters that are output from the sensors will then be measureed by a second device and indicated in a scale or registered digitally for subsequent storing, computation and displaying. Here are some examples of electronic sensors.

    Temprature sensors: An old device to measure temperature is a termocouple. This conist simply of two different metal parts fused together. The thermic energy in the metals tend to throw electrons over from one metal oiece to the other, but more in one direction than the other and then a thermocouple connected will get a voltage gap between the two metals that can be measured or that can be used to set up a current that can be measured. The voltage or current will vary according to temperature.

    Many materials have differnt conductivity in different temperatures. That is also true about materials. On can make temparature sensitive coils or diodes from such material that can serve as temperature sensors. (To be continues...)

     

    Resistors

    A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in accordance with Ohm's law: The electrical resistance is equal to the voltage drop across the resistor divided by the current through the resistor. Resistors are used as part of electrical networks and electronic circuits.

    One can use a multimeter or ohmmeter to test the values of a resistor.

    Most axial resistors use a pattern of colored stripes to indicate resistance. Surface-mount ones are marked numerically. Cases are usually brown, blue, or green, though other colors are occasionally found such as dark red or dark gray.
     

    Capasitors

    A capacitor is an electrical device that can store energy in the electric field between a pair of closely-spaced conductors (called 'plates'). When voltage is applied to the capacitor, electric charges of equal magnitude, but opposite polarity, build up on each plate.

    Capacitors are used in electrical circuits as energy-storage devices. They can also be used to differentiate between high-frequency and low-frequency signals and this makes them useful in electronic filters.

    Capacitors are occasionally referred to as condensers. This is now considered an antiquated term.
     

    The capacitor's capacitance (C) is a measure of the amount of charge (Q) stored on each plate for a given potential difference or voltage (V) which appears between the plates:


    In SI units, a capacitor has a capacitance of one farad when one coulomb of charge is stored due to one volt applied potential difference across the plates. Since the farad is a very large unit, values of capacitors are usually expressed in microfarads (F), nanofarads (nF), or picofarads (pF).

    The capacitance is proportional to the surface area of the conducting plate and inversely proportional to the distance between the plates. It is also proportional to the permittivity of the dielectric (that is, non-conducting) substance that separates the plates.

    The capacitance of a parallel-plate capacitor is given by:

    where ε is the permittivity of the dielectric (see Dielectric constant), A is the area of the plates and d is the spacing between them.

    In the diagram, the rotated molecules create an opposing electric field that partially cancels the field created by the plates, a process called dielectric polarization.
     

    Inductors

    An inductor is a passive electrical device employed in electrical circuits for its property of inductance. An inductor can take many forms, but most forms contain a coiled conductor, and inductor may be called "coils".

    Inductance (measured in henries) is an effect which results from the magnetic field that forms around a current carrying conductor. Electrical current through the conductor creates a magnetic flux proportional to the current. A change in this current creates a change in magnetic flux that, in turn, generates an electromotive force (emf) that acts to oppose this change in current. Inductance is a measure of the generated emf for a unit change in current. For example, an inductor with an inductance of 1 henry produces an emf of 1 V when the current through the inductor changes at the rate of 1 ampere per second. The number of turns, the area of each loop/turn, and what it is wrapped around affect the inductance. For example, the magnetic flux linking these turns can be increased by coiling the conductor around a material with a high permeability.
    The energy (measured in joules, in SI) stored by an inductor is equal to the amount of work required to establish the current flowing through the inductor, and therefore the magnetic field. This is given by:
    where L is inductance and I is the current flowing through the inductor.
    Electrical current can be modeled by the hydraulic analogy. The inductor can be modeled by the flywheel effect of a turbine rotated by the flow. As can be demonstrated intuitively and mathematically, this mimics the behavior of an electrical inductor; voltage is proportional to the derivative of current with respect to time. Thus a rapid change in current will cause a big voltage spike. Likewise, in cases of a sudden interruption of water flow the turbine will generate a high pressure across the blockage, etc. Magnetic interactions such as in transformers are not usefully modeled hydraulically.

    An inductor is usually constructed as a coil of conducting material, typically copper wire, wrapped around a core either of air or of ferromagnetic material. Core materials with a higher permeability than air confine the magnetic field closely to the inductor, thereby increasing the inductance. Inductors come in many shapes. Most are constructed as enamel coated wire wrapped around a ferrite bobbin with wire exposed on the outside, while some enclose the wire completely in ferrite and are called "shielded". Some inductors have an adjustable core, which enables changing of the inductance. Inductors used to block very high frequencies are sometimes made with a wire passing through a ferrite cylinder or bead.

    Small inductors can be etched directly onto a printed circuit board by laying out the trace in a spiral pattern. Small value inductors can also be built on integrated circuits using the same processes that are used to make transistors. In these cases, aluminium interconnect is typically used as the conducting material. However, practical constraints make it far more common to use a circuit called a "gyrator" which uses a capacitor and active components to behave similarly to an inductor.
     

    Electronic component color codes

    Electronic components are coded with a color band code. The code indicates figures. The interpretation of the figures, differr between the different component types. For resistors the figure indicate ohm. For capacitators they indicate micropharad.. The scheme is simple: The first two numbers are the first two significant digits of the resistance value, the third is a multiplier, and the fourth is the tolerance of the value. Each color corresponds to a certain number, shown in the chart below. The tolerance for a 4-band resistor will be 2%, 5%, or 10%.

     

    The Standard EIA Color Code Table per EIA-RS-279 is as follows:

    Color 1st band 2nd band 3rd band (multiplier) 4th band (tolerance) Temp. Coefficient
    Black 0 0 100    
    Brown 1 1 101 1% (F) 100 ppm
    Red 2 2 102 2% (G) 50 ppm
    Orange 3 3 103   15 ppm
    Yellow 4 4 104   25 ppm
    Green 5 5 105 0.5% (D)  
    Blue 6 6 106 0.25% (C)  
    Violet 7 7 107 0.1% (B)  
    Grey 8 8 108 0.05% (A)  
    White 9 9 109    
    Gold     0.1 5% (J)  
    Silver     0.01 10% (K)  
    None       20% (M)  

    Note: red to violet are the colors of the rainbow where red is low energy and violet is higher energy.

    As an example, let us take a resistor which (read left to right) displays the colors yellow, violet, yellow, brown. We take the first two bands as the value, giving us 4, 7. Then the third band, another yellow, gives us the multiplier 104. Our total value is then 47 x 104 Ω, totalling 470,000 Ω or 470 kΩ. Our brown is then a tolerance of 1%.

    Compunents use specific values, which are determined by their tolerance. These values repeat for every exponent; 6.8, 68, 680, and so forth. This is useful because the digits, and hence the first two or three stripes, will always be similar patterns of colors, which make them easier to recognize.
