Motor vehicle lights are a group of lights from red, yellow, green, three non-patterned circular units, guiding motor vehicles.
Non-motor vehicle lights from red, yellow, circular units of a group of light green bicycle pattern consisting of three inner guidance of non-motorized traffic.
When the green light to allow vehicles to pass, but the turning of the vehicle may not hinder the release of the straight vehicles, pedestrians.
Yellow light when a vehicle has crossed the stop line can continue to pass.
When the red light vehicular traffic.
In non-motor vehicle is not set intersection lights and crosswalk lights, bicycle and pedestrian lights should be in accordance with the instructions of motor vehicle traffic.
When the red light, turn right vehicle was released without prejudice to the vehicle, the case of pedestrians can pass.
- Q: Could someone tell if if I translated this paragraph correctly? Does it sound grammatically or stylistically good? The last employee leaving the premises must switch off the light and electrical equipment (except those that must run around the clock).
- The last employee *to leave the premises must switch off the *lights and *appropriate electrical equipment.
- Q: a small fire that is at the outlet
- CUT THE ELECTRIC SOURCE OFF BREAKER MAIN POWER SWITCH THEN USE WATER .OR CALL THE FIRE DEPT.
- Q: I need to know what object or whatever uses light energy that then leads onto electrical energy that then leads onto kinetic energy in order to work, what equipment does that? I said a Solar powered calculator but it was wrong so i'm really confused, could anyone help?:/
- I think the simple example is: When Light incidence to the photo cells(Viz: photo transistor or diode biased by this incidence of light), photo electric effect occurs-----Due to photo electric effect, photo transistor or diode produces eclectic current(i.e electrical energy) -----This photo transistor/diode acts like a driver of the audio oscillator and triggers the power audio oscillator------then produces audio frequency of specific or variable frequency according to the design----this audio oscillator frequency/ies signal hooked (interfaced) to the matched loudspeaker------Now we hear the sound which is a mechanical energy. I think this is one simple example for your question. Thank you. [You will find above:the conversion like this: Light energy--Electrical energy ----mechanical energy].
- Q: how we can design the power rating of any electrical equipment. as per my understanding only way is is to change the resistance of coil( winding if motor, filament if lamp).if it is correct then the equipment will be burn if resistance is low for low power rating. Eg. resistance of filament of 10 w lamp is lower than the resistance of 100 w. generally life of 10 w lamp is higher than 100 w. but in electrical point of view the life of high value of resistance equipment will be higher than the low value value of resistance. means, 10w bulb will glow longer time comparatively 100 w bulb. since 10 w bulb has high resistance , so this bulb's life should be higher than 100w bulb. can anyone explain how to design the power rating of any electrical equipment in line of other electrical parameters.
- Most equipment involves loadings on all the materials used and these materials have various load-carrying limitations. Design essentially balances these against each other whereby the materials' limitations often interact on the design. For existing design variation much empirical data and experience data will be available which will accelerate the design process but for a competely new design, the process may be iterative and toward the end may even need several prototypes to be built and tested. You can't merely change the resistance of a winding in a motor and get a higher rating. Things like core flux density and temperature-rise of insulation (affected by cooling, whatever type that may be) must all be checked. Lamp filament resistance is indeed lower for a higher rating but filament surface area (to get the radiation) and temperature will have to be decided which involves knowing and designing how the lamp radiates light and how it is cooled. The lifetime of a bulb can be quite precisely designed in, largely by the design temperature choice.
- Q: I want to know how good of a shot I have if my MOS is for electrical power production or electrician, that I can receive the first duty station on my wishlist.Yes Im aware that the needs of the service come first.
- Having an AFSC (Air Force)/ MOS (Army) in electrical areas makes that person pretty much in demand. While Electronic Techs are important, none of their equipment can operate w/o electricity. As for getting the first duty station on your wish list, it mainly depends upon the TOE (Table of Operations and Equipment) for a particular base. It not only tells operational procedures, but how many personnel of each rank are needed for that base.
- Q: Hi all, i wish to travel to the states soon and would like to bring some electrical items back, as-well as clothes when i travel to New York. From research i have already learned that these goods brought back into the UK can total ?340. But my question is this, if i travel to the US with very little luggage - no clothes or electrical equipment. Then in New York i buy a nice laptop, ipod touch, digital camera (but take the electrical stuff in with my hand luggage) how will they be able to know if the items i want to bring on the plane were in fact brought with me from the UK to US and were already mine?Also if customs say that i have to pay tax for going over the ?340 - how much will it be? say e.g. on a $2000 laptop?
- They might have a suspicion that you are importing items back to the UK (rather than having taken them there in the first place) when looking at the US-style electrical plugs. Given that these are not the same kind of plug as is used in the UK, you might raise suspicion when everything you bring back has US plugs (instead of UK plugs with a US adapter). I'd also note that failure to declare goods purchased abroad may make you liable for fines levied by HM Revenue Customs, as well as Customs seizing the goods. For purchases above the ?340 duty-free limit, the taxes paid depend on the total value. The second link below states that the duty paid on goods in excess of ?553 depends on the type of goods imported, and that you should contact HM Revenue Customs directly to find out what duty would be imposed.
- Q: How long did it take you to complete? What job do you have now? I am interested in going to school for that and wondering what type of jobs I might have.
- It took me 4 years to complete I am in a leadership development programing at a large aerospace company A lot of my classmates got jobs in the defense industry. Most are working in computer enigneering, rf design, or software
- Q: Affect Health? Noise problem?
- Depends on the devices, I lived below a cell tower (literally 1m over head, installed on the top of my building). After doing as much research as I could on it, I found that no one really knows for certain the effects of radio waves on humans. If your major concern is just large voltage electricals, the greatest risks are fire, a small magnetic field might interfere with your devices occasionally, and constant low hum.
