137) Electromagnetic Induction After Oersted's 1820 discovery that electric currents create magnetism, it was obvious that in some way magnetism should be able to create electric currents. This discovery of electromagnetic induction, in 1831, by Michael Faraday and Joseph Henry, was one of the most important of the 19th century, not only scientifically but also technologically, because it is the means by which nearly all electric power is generated today. 138) Alternating Current Electromagnetic induction makes it easy and natural to generate alternating current. Use of transformers makes it practical to distribute ac over long distances. Alternating current circuits obey a different equation identical to the harmonic oscillator resonance equation. |
ISC REF-DOT Reflexite Retroreflective Conspicuity Tape is a DOT-compliant prismatic conspicuity tape with 5-year durability used for commercial truck and trailer marking. This tape is an economical and effective alternative to the 10-year products when retrofitting older equipment. The tape comes with an aggressive pressure-sensitive adhesive backing that is designed for application to bare and painted metals, fiberglass, structural composite materials and more. It resists edge lift due to repeated mechanical and hand washing. The tapes are made from fully metallized, UV stabilized polymeric film, 2 mils thick. Single ply, not open cell, construction means no edge sealing is required so edges will not turn black with time and exposure as can happen with open cell construction. Reflexite Conspicuity Tape is a tough weather and solvent-resistant (including petrol and diesel) product designed for rugged outdoor use on the sides and rear of trucks, trailers, buses, agricultural equipment, utility vehicles, automobiles and all types of mobile and industrial equipment. Also intended for application to medium and heavy-duty commercial vehicles including towing and recovery vehicles and a great variety of vocational work trucks, including but not limited to construction vehicles, refuse haulers, step vans, utility trucks, tank trucks, auto carriers and more. The tape improves vehicle visibility from a variety of angles at night and in conditions of poor visibility, giving motorists increased reaction time. Because the product is thin and flexible, it can be easily applied to flat and curved surfaces. |

What can be said about a Surface Mount blinky kit? The BL2 is the revival of our classic BL1 blinky kit in a new modern form! Yes, two LED's that blink, just like our original blinky kit that has made us famous, but this one is subminiature, and is designed with SMT components! Why, you ask? Besides the obvious, a really neat, super bright attention grabbing display, there's no better way to learn how to work with SMT components! Don't worry, we even include spare SMT chips for when you goof up! When complete, the BL2 provides alternating super bright red and blue LEDs. Runs on 6VDC, and we include two LR55 button cells and a cell holder to mount on the backside of the board. It's one complete unit! If you don't want SMT LED's you can also use regular T1 3/4 LED's (included). If you want to learn what SMT is all about, the BL2 is for you! (You ll definitely want to keep your reading glasses handy when you build this one!) |
