10-12/Electronic Components April 8, 2020 10-12/Digital Electronics Lesson: 4/8/2020
10-12 PLTW Engineering 10-12/Electronic Components April 8, 2020 10-12/Digital Electronics Lesson: 4/8/2020 Objective/Learning Target: Students will be able to read the resistance value in Ohms of a common resistor and identify common electronics components. Resistors •. Resistors are an electronic component that resist the flow of current in an electrical circuit • They are measured in Ohms (Ω) • The different colored bands represent how much current flow that specific resistor can oppose • They are useful for reducing current before indicators like LED lights and buzzers. Resistors To read the resistors we use a Color Code Table 1. Starting at the end with the band closest to the end, we match the color with the number on the chart for the first 2 bands. 2. The 3rd band is designated as the multiplier. This indicates how many zeros to add to the number you got reading the first to bands. 3. The 4th band is designated as the tolerance. This tells us how much the actual resistance value may vary from what is represented on the chart. Resistors Lets do an example using the Color Code Table Starting at the end with the band closest to the end, we see the 1st band is Red, 2nd band is Violet. So, we have 27 so far. Next is the multiplier. In this case Brown, or 1. So we only add 1 zero. This puts the value of the resistor at 270 ohms. Finally, the tolerance is Gold or +-5%. So overall, the value of this resistor is 270Ω +-5% Capacitors • .Another common electronic component are capacitors. -

It is the spice I cannot identify, the dream I cannot remember, the way I touch my bare knee in the dark and wonder, "Is it mine?" .

The pressure sensing is achieved by incorporating a quantum tunnelling composite material composed of graphite nanoparticles in a rubber matrix into the multilayer nanostructure of a printed organic thin film transistor. This printed device was able to convert shock wave inputs rapidly and reproducibly into an inherently amplified electronic output signal. Variation of the organic ink material, solvents, and printing speeds were shown to modulate the multilayer nanostructure of the organic semiconducting and dielectric layers, enabling tuneable optimisation of the transistor response. The optimised printed device exhibits Citation: Griffith, M.J.; Cooling, rapid switching from a non-conductive to a conductive state upon application of low pressures whilst N.A.; Elkington, D.C.; Wasson, M.; operating at very low source-drain voltages (0–5 V), a feature that is often required in applications Zhou, X.; Belcher, W.J.; Dastoor, P.C. -
Light-Emitting Diode - Wikipedia, the Free Encyclopedia
Light-emitting diode - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Light-emitting_diode From Wikipedia, the free encyclopedia A light-emitting diode (LED) (pronounced /ˌɛl iː ˈdiː/[1]) is a semiconductor Light-emitting diode light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting. Introduced as a practical electronic component in 1962,[2] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness. When a light-emitting diode is forward biased (switched on), electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of Red, green and blue LEDs of the 5mm type 2 the semiconductor. An LED is usually small in area (less than 1 mm ), and Type Passive, optoelectronic integrated optical components are used to shape its radiation pattern and assist in reflection.[3] LEDs present many advantages over incandescent light sources Working principle Electroluminescence including lower energy consumption, longer lifetime, improved robustness, Invented Nick Holonyak Jr. (1962) smaller size, faster switching, and greater durability and reliability. LEDs powerful enough for room lighting are relatively expensive and require more Electronic symbol precise current and heat management than compact fluorescent lamp sources of comparable output. Pin configuration Anode and Cathode Light-emitting diodes are used in applications as diverse as replacements for aviation lighting, automotive lighting (particularly indicators) and in traffic signals. -

The LED’s range in wavelength from 470nm to 940 nm. The emission spectra will be observed with a Red Tide Spectrometer coupled to the LED’s with a fiber optic cable which can be positioned right above the LED. The peak wavelength of the emission curve will be measured using the spectrometer. The voltage to the LED can be varied, and a voltmeter will be used to measure the voltage at which the LED just starts emitting, which should be close to the bandgap. The energy of the emitted photons should be close to the bandgap voltage multiplied by the electron charge, and should also be equal to Planck’s constant multiplied by the photon frequency, allowing for a calculation of Planck’s constant. -
History of the Fan
History Of The Fan By George Woolliscroft Rhead History Of The Fan CHAPTER I THE ORIGIN AND USES OF THE FAN IN the beginning, before the human advent, when the earth was peopled only by the Immortals, a bright son was born to Aurora, whose soft and agreeable breath was as honey in the mouth of the gods, and the beating of whose gossamer wings imparted a delicious coolness to the air, moderating the heat of summer, and providing the first suggestion of, and occasion for, the dainty little plaything we have under consideration, somewhat waggishly described as a kind of wind instrument, not, perhaps, so much to be played upon as to be played with, and invaluable as assisting to follow out the wisest of the Sage’s maxims when he bids us keep cool. This delicate toy, this airy creation of gauze, ivory, and paint, frail and fragile almost as the flowers kissed by Aurora’s son, endowed apparently with the gift of perpetual youth, may claim a lineage older than the Pyramids; having its origin and being in the infancy of the world, before the birth of history, in that golden age when life was a perpetual summer, and care was not, when all was concord and harmony, and old age, long protracted, was dissolved in a serene slumber, and wafted to the mansions of the gods, the regions of eternal love and enjoyment. It was in these halcyon days that the human family sat in its palm groves, which afforded not only refreshing shade, during the hours when the sun is at its height, but also provided the precursor of this ‘Servant of Zephyrus’—serving further to temper those beams which are the source of all life, and light, and music, for are not all the learned agreed with the late Mr. -
White Paper Basic Switches
White Paper Issued By: Issue Date: March 2019 Basics of Basic Switches General Knowledge of Basic Switches Introduction Sensors in the past were considered one of the common electronic components used as complements to the functions and performance of electric appliances, machines and mechanical equipment. Today, with the advent of IoT, sensors and other electronic devices directly connect to the Internet and will play a vital role in the future IoT society - not limited to merely an electronic component that plays a complementary role. “Basic switch” is a mechanical sensor that detects (senses) the presence or absence of an object as well as its position by activating a plunger when the object physically comes into contact. With the emerging IoT, Omron’s basic switches have been widely adopted for position detection installed in customers’ newly developed electric appliances, machines and mechanical equipment. Furthermore, electrical signals outputted from the basic switch that indicates normal and abnormal conditions when detecting positions can be transmitted to remote monitoring systems over the Internet. Definition The following is the definition of a basic switch provided by the Nippon Electric Control Equipment Industries Association (NECA). “A miniature switch, also known as snap-action switch, achieves a very small contact separation and the contacts are enclosed in a case in which these contacts open and close according to the specified movement and force. An actuator is equipped outside the case ”(Figure 1) With a snap-action mechanism, the contacts will instantaneously switch at a specific operating position regardless of its speed. The mechanism allows the basic switch to operate using a specified movement and force.
