Q:I need the wiring diagram for the factory radio of a 2008 ford explorer. i need to know which wires are for the back speakers so i can connect my Hi-Lo converter to it!? thanks

It would be easier to install an Line Output Converter on the rear speakers if the sub is going to be in the back. I personally would buy the harness pigtails for the speakers and the speaker harness. This would eliminate the need of cutting the factory wiring. You just pull the plug off the speakers in the back, and plug in the mate plug that will have a 2-wire pigtail that you would wire to LOC. The other plug with the pigtail would be plugged on the speakers.

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:If 46 m of nichrome wire is to have a resistance of 12.0 Ω at 20°C, what diameter wire should be used? in mm

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 Nichrome 150e-8 Ω-m 12 = (150e-8 Ω-m)(46m)/(πr?) solve for r, which would be the radius of the wire in meters. change to mm, and multiply by 2 to get diameter. .

Q:I accidently spilled soda all over a bunch of wires and controllers. I cleaned the controllers off and they're not sticky, but what should i do about the wires?

Specify wires.

Q:Two wires, 2.44 m apart, both carry current 2.2 A toward the bottom of the screen. The right wire is extremely long, and the left wire is 0.36 m long. What is the magnetic force on the left wire?

Magnetic force, F = BIL --------(1) where B is the magnetic flux density of the magnetic field caused by the right wire, acting perpendicularly to the left wire in Tesla I is the current in the left wire in Amperes L is the length of the left wire in metres To find B (due to the right wire), you have to use the formula B = (?0)(I)/(2πr) -----(2) where the I in this case is the current in the right wire, r is the distance between the two wires, and ?0 is the permeability of free space, numerically defined as ?0 = 4π×10?7 using eqn (2) so B (due to right wire) = (?0x2.2)/(2πx2.44) = 1.8x10^-7 T using eqn (1) and the value of B calculated above F = (1.8x10^-7 x 2.2 x 0.36) = 1.43x10-7 N

Q:The new light has 1 live, 1 neutral 1 earth wire, do i remove the earth connect the reds if so what about the 2 blacks?

Its quite simple really you dont. If the fitting in question has a requirement for an earth connection ie its made of metal then it requires an earth to be fitted. If there are no earths at your light fittings then you have have very old wiring and should be considering having a rewire as you are way out of date. As to the wiring you have at the ceiling now one of the reds is the live feed and assuming its twin cable and not single the black wire of the same cable is the neutral and the other 2 wires go to and come back from the switch, trick now is which is which.

Q:Say you have a 5 cm current wire carrying 10 A going from left to right. Directly 1 c.m below the left end of this wire is a long wire that is perpendicular to the first wire and goes out of the page. What is the net force on the 5 cm wire?I've tried using F=ILB with the I of the first wire and the B of the second wire.

I didn't read the question so I was carefully working out the force. The wire is perpendicular to the first wire, so using the right hand rule you discover that the field it creates is PARALLEL to the first wire at this left end. The magnetic force is caused by the component which is PERPENDICULAR to the wire which is in fact zero. So there is no magnetic force at this point. As you move along the wire you get a diminishing amount of magnetism caused by the wire which is going out of the page but that field has a component which is DOWN the page. Therefore that part of the wire experiences a force which is into the page. ( take your right hand, put the thumb along the wire pointing to the right, the fingers point down the page, the palm points into the page which is then the direction of the force) I would be surprised if you were required to work out the magnitude of the force in this context. You can't use F= ILB because both the magnitude and the direction of the field varies at different points along the wire. If the perpendicular wire had been directly below the middle of the other wire there would have been no net force. If you were of a level where working out the force was appropriate you would need to set up the formula for B at various points along the wire, taking the vertical component only and integrate this over the range from 0 to 5 cm. Not a trivial mathematical task.

Q:Does anybody know of a How to Guide... or a tutorial or something to help me wire a Telecaster for a project? I'm pretty new at this and I want to make sense of the wiring diagrams I've found and make sure I don't screw anything up, thank you.

extremely tough point. look into from google. just that could help!

Q:plzzz let me knw tis !! GRADE 10 PHYSICS- importance of live wires neutral wires !!!!!!!!!!

These two wires provide the voltage difference (called potential difference) that is responsible for driving the current through an appliance. Live and neutral are terms most commonly use with mains electrical supply .. they are equivalent to + (live) and - used with batteries and other DC sources. The live wire is at the higher voltage (most dangerous) and the neutral is usually close to ground voltage (0 V). Both wires together form the complete circuit required for the current .. from the supply (through the live wire) to the appliance and back to the supply (through the neutral wire). In a mains circuit a switch is always connected into the live wire so that the high voltage is disconnected from the appliance. A switch connected in the neutral wire prevents the appliance from working (so it appears to be off) because there is a break in the circuit .. but the high voltage is still connected to the appliance which may be dangerous. For the greatest safety a switch should disconnect both live and neutral wires at the same time.

Q:Will you please remove any of the wires? The edge of the body, which is made of wire or what? Is it copper or iron?

Residential electrical wiring generally uses only one layer of plastic insulated copper core wire, which is usually worn in plastic pipes or steel tubes, concealed in the wall, in order to avoid mechanical damage. Conductor part of the conductor in the structure of solid and twisted two kinds, and its components are pure metal, alloy, coating and enameled wire. (referring to the Baidu encyclopedia wire structure) metals cannot ignite, and copper has a melting point of more than 1000 degrees! No electricity, no electricity, of course. Does not rub with wood to produce electricity or sparks.
