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.

- Q: I have worked there as an electrical engineer but in design for a consultant. I would like to know what are the major things to account for (DB's, wires and cables, ducts, conduits.) and how to estimate them for a typical 6000sq.ft 2 floor villa
- If you have the design drawings, you simply have to make a material take-off list. The main drawings are: General Layout Grounding Layout Electrical Equipment Layout / Schematic Riser Diagram (Fire Alarm) Lighting Layout At the very least, you need to have the General Layout drawings (to know how many rooms you've got) and you need to know the electrical levels since some houses might require 380/480 3-phase for elevators and large electrical equipment. Working room by room, you will estimate cable and conduit lengths, the number and specifications of the DBs, number of lights, outlets, switches, buzzers, intercoms, smoke detectors.
- Q: If it is, why?
- The answer is no. There are resistances between electrodes placed in the ground anyplace on earth. The resistance varies with the composition of the soil. Grounding grids are engineered for industrial and commercial facilities. These usually consist of a grid of heavy gauge cable connected to a matrix of ground rods driven in the ground , sometimes to great depth. These ground rods are in a 6 to 12 inch diameter pipes at the ground level. There are special connectors which are used to test the resistance on scheduled periods. Individual electrical equipment and buildings are grounded directly to the grid using a method of welding the cables with a mold and a powder which is fired to create a short lived, very intense reaction. The individual cables connected to the structures and equipment is with a special split bolt which is threaded directly to the equipment. The cable is placed in the split and a nut is screwed on the free end of the bolt to compress the cable. Once while assisting in plant startup in Michigan, we had to drive the grid ground rods to a depth of 80 feet to obtain a satisfactory ground.
- Q: does adjusting the router's position about an inch or adjusting the direction of the antenna affect my laptops browsing speed?
- Not so much. But moving it away from other electrical equipment will make the signal travel farther. Also keep it as far from the cordless phone and things like that. Other digital devices, and concrete/brick walls really break it down. If you are connected to the access point at even a fair signal, you will probably be using all your internet connection speeds' bandwidth. Having a better signal wont make it faster, unless it is actually disconnecting on you.
- Q: Conduct regular maintenance tests for the electrical equipment.The following actions should be taken to reduce the probability of potential electrical deficiencies at this facility.The Hazard
- potential electrical deficiencies means the possibility that this facility will not work due to electrical problems in other words, future problems caused by lack of maintenance on the electrical equipment. Therefore, the sentence could be rephrased as follows: The following actions should be taken to to make sure all the electrical equipment stays in good working order.
- Q: I am about to finish my BS in Electrical Engineering and was considering getting a MS in EE but considering how the economoy is and the fact that the Bureau of Labor Statistics say it should grow slower than average. This being said what do you guys think is the most prudent thing to do in my case. Go for an MS Engineering Degree or start out with another degree maybe in healthcare.
- I agree with Bimmer, if you decide to stay in school, go for the MS in EE But MS can be quite different from BS. more pure math. and mainly RD, papers , thesis if you like sort of work go for it. Otherwise, go find a job There is a lot of job that are not advertisedespecially in EE.
- Q: a. nuderwriters laboratories b. national fire protection association c. national eletrical contractors association d. institute of electrical and electronics engineers
- a. underwriters laboratories
- Q: i am very interested in pursuing a degree in any type of engineer that designs military equipment it can be communication equipment, guns, tanks, grenades, any type of equipment im just wondering what engineer or designer does that type of stuff
- To manufacture military equipment all engineering and sciences are used. For capital equipment mechanical engineers, electrical/electronic engineers, manufacturing engineers. For development of new systems scientists of all types. These days things are so complex it is generally a team of multidisciplinary people involved not just one type of engineer
- Q: I have been trying my best to put some few things together as per building electronics and electrical equipment but i really lack circuit diagrams that can put me through. i presntly need a circuit diagram of an inverter with atleast 20kVA output.
- pspice
- Q: I am a freshman of the engineering program at the university of Wyoming. Right now I am going into electrical because I wanted to stay in Wyoming and I thought that it would be easier to get a job in the production and distribution of electricity through something like Rocky Mountain Power. I don't mind doing the math and physics for electrical, but I am thinking that I would enjoy becoming a mechanical engineer. At the moment I believe mechanical is much more hands on, designing parts and testing them. I don't know what these two would lead into though. Electrical makes more money, but is that worth it? Also how hard would it be to get a job in this region with mechanical?
- both electrical and mechnical are good field.
