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: if my electrical equipment has a fuse; does that not mean it's protected?is it just the power grid that goes down?
- The solar flare distorts the earths magnetic field. The basis all power generation is motion of a conductor through a magnetic field. So when the flare distorts the earth's magnetic field all the cables that form the electricity supply grid act as conductors in the earths distorting field. This induces currents that can lead to voltage spikes damaging equipment. The earths field is so big and ubiquitous and the distortion so rapid that often the surges as so sudden and huge that damage is done before systems designed to protect the grid can operate.
- Q: Do they design circets for the electricity? If not, what do they design?
- There are many different areas of specialization in electrical engineering.
- Q: I am wondering what happens when you have accidentally connected the negative cables to positive and the positive cables to negative. I have boat that has to two marine batteries and i am wondering if you were to do this will it screw things up and break things?
- Hmmmm The only approach to comprehend for sure if that fried the the circuits could be to check out it out with the proper adapter. I would now not use the adapter with the overrated voltage, why danger it extra? Just take the one you firstly used, reduce the output cable and splice the wires collectively the opposite method to reverse the polarity of the plug. That would clear up your main issue.
- Q: how is this possible?
- Theoretically, yes they do. Practically, no. If load resistance decreases, V out decreases some, if load resistance increases, V out increases some. All wires have a resistance, even the wires from a supply point to an electrical outlet.
- Q: EMP is a byproduct of a nuclear explosion. It can cook solid state electronics and computers. The great danger is that nuclear air bursts can take down the computers that manage our banking, our record-keeping, and even the ones that manage our automobiles.The military services have taken some steps to protect their electronic systems from EMP, mainly by shielding. However few of our civilian electronic systems are protected in any way from this threat.Obviously there are two ways to deal with it right now. One is to prevent the explosion by deterring a nuclear attack. The other is to find some way to protect our senstive electronics.What should we do, and what can we do starting today?
- I would love to live in a non technological world like the victorian times when toilets were amazingly comforting and social interaction with the women was the talk of the night. Oh sorry, i forget this was about america, im sure with the budget you have to spend on this it will be enough to make it a top priority so it should not be too long, unless they are keeping it a secret from the public eyes till doomsday arrives to see if it works. Industrial work will be hard work, but i will be sure to have a jolly good time pumping water out by hand and employing kids to sweep chimneys. Also a few media tip offs say iran has enough for 5 nuclear weapons so if all air defense forces chip in around the world it will be a russian roulette to see what the outcome is to where they land. Whats to say that they might become duds and not explode? Also how long does the EMP last for? if it instantly kills the electronics surely they have replacement parts hidden away in a nuclear bunker where some tunnel rat worker will guard it till someone gives it a lick and tests them to see what a masterpiece the human race can acheive.

- Q: I just don't understand it, what does it mean when people say 3 phase or 2 phase Voltage, I know higher phases are used to power bigger more voltage demanding things but what does it mean?Can you get both AC and DC in each phase?Is phase just basically saying higher phase higher voltage for higher voltage equipment?How do you convert between phases?Are high phases created with the use of transformers or can they be created directly from things like wind turbines?What is the maximum and minimum phase?How does the phase effect the amps?
- Let me explain briefly about the Electric power source and what it has. We get electric power source normally from power station where it is produced by means of Electric power generators. The generator has an Armature which comprises three windings (say coil). Each winding has two ends and all these ends are connected with each other. From Armature windings 'THREE LINES' are drawn to transmit the Electric power source. {Power station produces very high voltage (Electro Motive Force) and transmit the source through over head lines to the various step down Transformers where it is finally step-ed down to low voltages ranging from 600 to 220 volts and supplied to us.} As said above the 'THREE LINES' that Carry's the electric power source from the power stations to us are said as THREE PHASES. VOLTAGE is the unit of the 'Electro Motive Force' (EMF) which is supplied to us from power sub station. What is 220 and 120 volt ? Power substation Supply power source to us by means of 4 wires where the three wires which are called Phases as said above and the fourth wire is called as Neutral. The phase wires carries power source where as Neutral wire carries no power source. America and other countries which follows American Standard, use a phase wire and a neutral wire for 120 volt Supply especially for lighting loads and two wires of phases are used for 220 volt Supply for appliances etc., If you measure the voltage between phases it will read 220volt and phase to neutral it will read 120 volt. Manufacturers of motors, home appliances, electrical equipments, etc., are the deciding authority to Communicate the voltage requirement of their PRODUCTS based on the way they made them. We can find this detail in the name plate of the equipment. Regarding AC and DC Supply. Batteries are made to Supply DC Supply and it can be used for AC equipments with suitable invert-or to change DC to AC.
- Q: If an electrical equipment is designed for 220V at 60Hz, can it be used in a country which uses an electrical system of 240V at 50Hz. I'm not sure how true is this, but I've heard that the voltage would not be a problem but if the frequency is less, electrical equipments with motors will not be able to run at 100% performance which means the efficiency drops. Please enlighten me~Thank you
