Q:Both wires are black. One has what looks like white paint on it.

In Knob and Tube wiring system the black is the hot wire. KT is no longer an approved wiring since the insulation will deteriorate over the years and no ground wire is present. It should be completely removed as soon as possible. The wire with the white paint is probably the neutral wire. To verify this, take a conductor from the neutral buss of the panel and run it to the outlet, then use a solenoid tester to read the voltage.

Q:Wire 1 and wire 2 are made from the same metal. Wire 2 has a larger diameter than wire 1. The electric field strengths E1 and E2 are equal. A) Compare the values of the two current densities. Is J1 greater than, less, or equal to J2?B) Compare the values of the currents I1 and I2. Is I1 greater then, less or equal to I2?

The current will be more dense in the smaller wire. The value of the current is inversely proportional to the resistiance of the wire. Resistance = resistivity * length / Area since the wires are of identical material and length, the only thing left to vary is the cross-sectional area. Area is proportional to the square of the radius (diameter), so the current will be proportional to the square of the diameter. I2 is proportional to I1^2 I2 is larger than I1 .

Q:How do you properly wrap copper wires? We have been using electrical tape and it's melting the tape. This is in a camper, and it's in the electrical box. We're using this tape because the wires kept touching and arcing off of each other...I'm guessing :/

If the wire is not heavy enough it will heat up from the amount of current through it. If there is a short circuit somewhere, the wires will heat up regardless. It may not be rocket science, but it certainly is electrical engineering.

Q:how to connect the wiring from car stereo to amplifier

The consistent potential twine is nearly a small direct line from the battery, as in it is many times warm, yet once you have been placing it to the useful of the upload-ons it could have in basic terms been becoming a circuit. it is to no longer say which you probably did no longer short out the wiring some incorrect way and that i'm unsure what the twine grew to become into which you genuinely touched with the consistent, yet it is many times run from the useful part as a relentless, till you have a grounded useful electric equipment on your motor vehicle. you does not in an '89 Escort till you probably did that your self. Wiring could be with any luck fused, even regardless of the indisputable fact that i do no longer understand how some distance back the fusing may well be, no count number if or no longer this is each and every of the previously to the fuse field or a separate fuse closer to the wiring.

Q:The black wire is called ground but what is the red wire called?

In single phase AC circuits it's hot (ungrounded). In three phase AC circuits it's A phase. In DC circuits it's positive.

Q:I need a wiring diagram for a 1983 honda rebel, its a 250cc parallel twin, i really need the ignition wiring diagram but i can't seem to find one. If anyone knows the letters (xx250,xx125) then that would help to. Thank you in advance.

manuals.. okorder /

Q:-note-NOT . resistance wire.resistance OF A wire :)lol sorry, just had so many people give me resistance wire.thats not what i want :Li want ..what is the resistance of a wire?its for my science :) pleasee help

It okorder /... Good luck in your studies, ~ Mitch ~

Q:How can it be possible to create a high voltage and have a small gauge wire? Example: 3gj or 3000mw in a small wire (just an example)

Voltage don't matter. It's the amps that will kill the wire. Just have really high voltage and low current and you can have lots of power going through smaller gauge wires. That's how it's done with overhead power lines.

Q:How much wire is required?

R = p*L/A Solve for L, length of wire. L = R*A/p p - resistivity of nichrome A - pi*(1/64)^2 R - 2.2 ohm

Q:I have looked up wires for this car but the ones that I have looked up tell me i should have different colored wires. These are the wire colors i have:yellowyellow/blackorangepurple/whitewhiteblue/redgreen/blackpink/blackred/blackblue/orangeyellow/redwhite/redgreen/orangePlease Please Please help me!Thanks,Ash

The wire coloring (wiring diagram) for my friends 1997 Mazda Protege LX was as follows: Car Radio Battery Constant 12v+ Wire: Blue/Red Car Radio Accessory Switched 12v+ Wire: Pink/Black Car Radio Ground Wire: Black/Yellow Left Front Speaker Positive Wire (+): Blue/Orange Left Front Speaker Negative Wire (-): Violet/White Right Front Speaker Positive Wire (+): White/Red Right Front Speaker Negative Wire (-): Yellow/Red Left Rear Speaker Positive Wire (+): Orange Left Rear Speaker Negative Wire (-): Yellow Right Rear Speaker Positive Wire (+): Green/Black Right Rear Speaker Negative Wire (-): Green/Orange
