Q:What role does the neutral wire play?

An electrical circuit requires at least two wires, whether it be ac or dc. In mains ac, one of the wires is connected to ground for safety. This is called the neutral. So the circuit will still work without the neutral connected to ground but not be so safe. The reason the neutral makes it safer is that a current will flow in the event of a fault on the hot wire and cause the protection (fuse or breaker) to operate.

Q:I just read an article about a man who was electrocuted by a live overhead wire while trimming a tree. Horrible. My question is I see squirrels running on all the overhead wires. How do they not get electrocuted?

Electrocution happens when electricity finds a way to ground. Squirrels are not grounded so they don't get shocked. Ever watch the Discovery channel? They've shown how the power company works on high voltage lines without shutting the power off. A helicopter hovers next to the power line while a technician reaches out to the power line with a probe. Once contacted the helicopter and the technician are at the same potential voltage so nobody gets shocked. However, during approach they are NOT at the same potential. That's the reason for making contact with he wire with a probe first. So that the technician doesn't take a big hit when he first touches the live wire. So squirrels, birds, rats - anything that can land on the wires doesn't get electrocuted. But if an animal touches the wire AND ground (or another wire), it's all over in a blinding flash. Hope this helps. 'av'a g'day mate. '')

Q:Consider a copper wire 1 mm in diameter providing the power needed to run an appliance drawing a 4.8 kW at 12 V. Assuming that no heat is radiated away from the wire while the current flows:A. What will the temperature of the wire be after the current has run for 1 second through the wire?B. What will the physical condition of the wire be at that time?(The wire was initially at 20 degrees C)

Assume the wire is 1 meter long. Resistance of a wire in Ω R = ρL/A ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m? A = πr?, r is radius of wire in m resistivity Cu 17.2e-9 Ω-m or 17.2e-6 ohm-mm R = (17.2e-6)(1000) / π(0.5)? = 0.022 ohms Appliance current is 4800/12 = 400 amps Power is I?R = 400? x .022 = 3520 watts. Problem, this power is at a level almost as high as that of the appliance. In other words, the wire is too thin to sustain that power level. .

Q:So ground wire, start anywhere i suppose?Where does ground wire hook up too?why you need to ground out your system?Only need 1 ground wire?

yes only one from the amp to the battery with an inline fuse

Q:my rabbit is chewing wires and in one area in my room there are like 300 wires i was just wondering if i can spray something on the wires cause i thought i saw something that said that please help!!!!

you ought to purchase plastic twine covers at OKorder or objective or probable any workplace merchandise shop. If achieveable, bunch the wires and circulate all wires up or out of return and forth routes as a precautionary degree, disguise them or block get entry to to them (as in case you have not already tried that ;o). Plexiglass, or previous pillows or towels (which you would be able to get at a thrift save) ought to conceal the wires until she's use to not biting them. one in all my bunnies use to consume paint precise off the wall - I had to purchase Deer Fence (any animal repellent ought to do) to end him from doing it. It worked, the abode smelled aweful for a collectively as, even with the shown fact that it broke the habit. All of my bunnies use to consume wires, wallpaper, and carpet while they have been youthful. They grew out of it after 2ish - thank goodness! good success!

Q:What is the difference between carbon fiber and wire heating?

Long life: because of the characteristics of carbon fiber made its corrosion resistance, durable characteristics, and metal heating wire aging, corrosion, and short service life

Q:i have old wiring for a stove that iam putting in ,a new box but i have only 3 wires 2 of them are white and 1 black how should i connect on a 4 wire receptacle? on the receptacle 1 white 1 green, 4 a ground then it says x then y ???????

I would suggest that you go and pick up the correct box. You should 4 wiring box if you are using 220 volt system. white,red,black and green

Q:the sensor part has 4 wires,(2 white,1 black and 1 red)each light has 1bl.and 1white

The other answer that has directions doesn't sound right for your case. Do you have a link to the actual product? Two white wires sounds strange, unless they have stripes or something to differentiate them. It seems pointless to have 2 wires that would just be connected together. Give me a link or the actual brand/model number and I'll give more information.

Q:i hav a 2000 explorer and just got a new head unit and bought a wiring harness to hook it up. on the wiring harness that's supposed to be plugged in to the truck there are 2 illumination wires, 1 of them is the illumination ground .Out of my new stereo there is only the illumination wire not an illumination ground wire. where do I put the illumination ground ? also i have 2 ground wires coming from my new deck 1 is 12v ground and the other is a chassis ground can i just hook them together?
