Q:I have a copper colored wire, a black wire, a red wire and white wire in the little box in the wall?? please help.

Heres okorder /... I hope this hleps.

Q:2 long striaght wires (20m each) ,each having a 1.0A current going up.The distance between the two wires is 1.0m(a) what is the magnetic field (magnitude and direction) at a point o.50m left of the wire 1?(b)what is the magnetic field (magnitude and direction) at a point 0.6m right of Wire 1?

Assuming Wire 2 is to the right of Wire 1: a) Bwire1 = (u*I)/(2*pi*r) = ((4*pi*10^-7)*1A)/(2*pi*0.5) = 0.000004 Bwire2 = 0.000000424 Btotal = 0.000004424 (away from wire 1) b) Bwire1 = 0.000003333 Bwire2 = 0.000005 Btotal = -0.0000017 (toward Wire 1)

Q:A wire has a resistance of 21.0 ohms. It is melted down, and from the same volume of metal a new wire is made that is three times longer than the original wire. What is the resistance of the new wire?

The resistance of the new wire is (in terms of its length, area resistivity); R2 = pL2/A2 And the resistance of the original wire is; R1 = pL1/A1 The ratio is;(resistivity will cancel because its the same for both situations) R2/R1 = L2A1/L1A2 given L2 = 3L1 R2/R1 = 3A1/A2 To find the new cross-sectional area ,require the volumes to be equal; L2A2 = L1A1 3L1A2 = L1A1 A2 = (1/3)A1 Sub this into the R2/R1 equation to get; R2/R1 = 9 R2 = 9R1 = (9)(21) = 189 ohms

Q:Why does a thin wire melt and a thick wire glow when put up to the terminals? Explain in terms of resistance and current. Thanks=]

The higher the resistance the more heat will be generated in the wire. A thin wire has a higher resistance in comparison with a thick wire of the same material in the inverse proportion to their cross sections (as long as the length remains constant).

Q:Please help,I have a 1993 Jeep Grand Cherokee LaredoThe wire harness on the hitch has 7 wires,The whole thing is shot,My Question is can i just wire in a 4 prong harness, On my trailer yellow is left turn-green is right turn-brown is stop tail, white is ground The Jeep has 7 wires a green-a tan- a brown w green stripe-a blue w red stripe-a red w blue stripe and a bigger light blue and a bigger black, can i splice into these or do i have to get a converter of some sort ,Any idea'sTHANK YOU

auto parts stores have adapters

Q:Ok so I bought a blower and barrow at the junk store... Figured I could use a v-belt to drive it with this old motor I have... Homemade dust collector!!! Anyhow I have no Idea how to wire it up... I know it probably needs a capacitor but thats about it... It's an Emerson... Has orange, blue, brown, white, and black. Any Ideas would be great! On the sticker it list three different speeds (rpms) So i'm guessing I don't need all the wires and some are just quot;taps.quot;

i think of you have enormously plenty responded your individual questions. The drain is clogged as they generally get with out each year maintenance or a minimum of two times a summer season pouring bleach in the path of the line. And besides, it has probable broken the blower motor. One issues for specific although, by no ability attempt and repair the unit or look at it with out first turning the capacity off to the kit which it variety of feels which you ignored to do. I additionally undertaking to assert that somebody has at one time replaced that blower motor because of the fact your description of the wires might point out that it wasnt production facility set up anymore.however the provider tech which you will might desire to call and time table an appointment with would be waiting to repair and replace mandatory aspects. go away something as much as the pros

Q:@topicAnd does the size of the wire matter in electrical consumption?

The size of the wire that matters in electrical consumption.

Q:my speaker makes a fuzzy or static noise while the scene has high or low sound. I cut my wire in half because I bought a subwoofer and we didn't get the wires with it. So I cut it. After all I didn't need the wire for the subwoofer. Could my speakers make such noises because of cutting a wire?

Shortening your speaker wire will not cause this problem. In fact, shortening your speaker wires should give you less static since there is less resistance. Most than likely, it's not your speakers causing the static sound, but your amplifier or receiver. You may be looking for a new one soon.

Q:My tail light work but when i hit the breaks everything go out. Any answers? Standard 4 wire

probably not a good enough ground connection make sure it is wired correctly white wire is the ground yellow wire is the left blinker and brake light green wire is right blinker and brake light brown wire is tail lights

Q:i am looking for a wire diagram for a 03 eclipse gts with an infinity factory radio and built in amp. i was curios if you can add another amp and sub to this system to give it a little more bass
