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:100 vac to 240 VAC 50-60 Hz 15 watts How can i calculate power consumption?
You have the number, 15 watts. but that is a maximum, the actual power will be less than that. If you need the actual power, you cannot calculate it, you have to measure it. .
Q:How to read a Commercial Electrical Service Panel?
I believe that the sum of the individual service panels can exceed the service capacity of the building just as the sum of the individual circuit breakers in a panel can exceed the capacity of the panel. It is allowable to assume that not every load will be using power at the same time. Near the meter, there should be a master circuit breaker or set of fuses that determine the ampere rating of the service to the building. In a large industrial facility, that location may accessible only to qualified personnel, and you may need to ask a qualified person to give you a description. You should state the voltage, number of phases and current or KVA available at the meter location. For a large facility, you may want to itemize the ratings of panels serving major spaces and/or verify that all major spaces have the same voltage and number of phases available. For large industrial facilities, you should also determine if the utility or the customer owns major outdoor electrical equipment that is on the property.
Q:electrical outlet issues?
Not a big problem first you have to find the short then get the ground wire working start by removing ALL loads on that circuit and pull the outlet covers then start with the wire disconnected at the breaker box using an ohm meter follow it as it was wired separating everything if needed to pin point short then when you got infinite reading hook back the wire and find the broken ground (sounds like a ground was hooked to a hot maybe
Q:career electrical engineering?
Well. it is very good major Oil and Gas companies need ur major since the instrumentation is controlling the whole units. Huge Essential System and very critical in any refinery such as: DCS : Digital Control Center. ESD: Emergency Shutdown. UPS: Uninterrupted Power Supply ( Electrical Equipment feeds instrument load) I think u have a bright future with this discipline if you have interests . And regarding these Subjects, i dont know much about control All the best
Q:what is principle of lightning arresters?
A lightning arrester is to protect equipment from getting damaged from a lightening charge. Electricity will go to the nearest ground and the best ground or negative side - which is the ground you are standing on. The positive side + is in the sky, the higher you go the higher the charge ( in the millions of volts ). Air is the best insulator for high voltage so you don't get electrocuted when standing under a high voltage power line, or in a airplane. The + and the - are trying to equalize so the negative side runs along the ground looking for the positive electrons, and the positive electrons are looking for the negative, like a magnet so when they get close enough, the negative charge (amps) goes up to the positive charge burning the air and making a path so the positive charge can get to the earth. If you ever watch lighting-stroke you will see a light flash go up before the positive charge comes to the earth. Lightning arresters protect your computer, TV, and all the electrical equipment you have. When hair stands up on the back of your neck, get out of there.
Q:Why is teflon used in laboratory equipment?
It does release toxins; however not much is affected by these toxins - except birds. The characteristic of teflon on pans, etc is that makes it so popular is that surfaces coated with it don't stick.
Q:How long would it take for the world to recover from a series of EMP nuclear attacks?
About 15 or 20 minutes maybe?
Q:When is my electrical equipment really off?
When you turn off modern Tvs from the remote, it will go to standby mode, there's still electricity on the circuit enough for the memory to remember your settings, like volume, time, the channel you've last watch before turning it off. When you turn off the switch from the wall or unplugging it, the Tv is now completely disconnected from the power source. You may loose personal settings, and when you plug it back on then it may function in the default settings. Leaving it plugged has advantages but surge, lighting, sudden voltage changes may damage it. So when you'll be out for days then unplug it from the AC outlet to play safe.
Q:what is AC and DC and how do they work?
DC is direct current and AC is alternating current. From the names, DC is constant voltage that gives us potential energy directly such as batteries and AC is alternating between positive and negative voltages and has a specific frequency usually 50~60 Hertz. The reason why most devices blow up when connected directly to AC voltage is due to the fact that AC has a higher voltage rating than DC, and most electronic devices operate at lower voltage and therefore you see most electronic devices with transformers in order to convert the high AC voltage to DC voltage. The case of the light bulb is that it can operate by AC voltage, since light bulbs needs the frequency of the AC voltage source in order to keep flickering, however our eyes do not keep up with the flickering speed and see it as constant light.
Q:what type of engineers design military equipment?
all of them basic weapons- ME chemical - ChemE but not really, mainly chemists electrical - EE
