Q:i want to attach a wire to my new speaker but when i cut the wire taken from my headphone, there are 4 wires in it, 2 are golden colored and the other two are green and blue but the speaker has only 2 points to connect the wires.Someone plz help me.

Just get some speaker wire its not that expensive ; go to Wal Mart where they have the TV's and ask for speaker wire or go to the hardwear store and ask for speaker wire or lamp cord thats polorized for the wire you have twist the two golden wires together at both ends and twist the blu and green together at both ends now use the golden for positive and the other for negative.....

Q:How do they differ from residential wiring?

Commercial and industrial wiring make extensive use of conduit, cable trays/ This entails explosion-proof or flame-proof fittings, along with the seals and other conduit fittings. Residential wiring, in most cases make extensive use of romex cables without any conduit. Other than these major and a few minor differences, the wiring is actually the same. This is the installation of cables/wires from the circuit breakers to the users. TexMav

Q:want to get ready to solderis the fuzzy stuff the wire? or the shiny (positive green and negative red color) the wire? sorry i know its a noob questionlet me knowthanks

wire is metal and metal is orange or silver . The fussy stuff is string

Q:During a lab experiment, a straight piece of copper wire is connected across the terminals of an AC generator and the current through the wire was measured. If the wire is removed and a part of it is tightly wound into a loop of many coils and the wire is then reconnected to the generator, will the measured current through the wire be greater, lesser, or the same as it was before the wire was coiled? Explain your answer.

Assuming the generator output voltage (RMS) remains constant the current will be less through the coil. By wrapping the wire into a coil it's resistance doesn't change but it's self inductance increases. AC in a wire produces an alternating (changing) magnetic field that is concentrated into a smaller space as a coil - so increasing it's strength and ability to link with the wire that produced it. When this changing magnetic field links (passes through) it's 'own' coils a self-induced 'back' EMF(voltage) is generated in the wire that opposes the 'forward' current from the generator (Lenz's law). If the geverator provides a pd = Vg and the back EMF = Vb, then the current in the coil is effectively being driven by a reduced pd = (Vg - Vb) .

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:What are some of the basic advantages of twisted pair wiring?

Lower noise due to inductively coupled current from interference sources, such as (say) a motor or AC power line. When a changing magnetic field is near a coil of wire, it induces a current in the wire. If that wire is your network cable, the current will be misinterpreted by the receiving NIC as voltage generated by the sender, which will cause packet corruption. With twisted pair wire, after a twist the magnetic field ends up creating a current in the opposite direction since the order of the wires has switched. Therefore, the current induced from adjacent twists of the wire ends up cancelling. (Assuming the magnetic field strength is consistent over the distance of 2 twists.)

Q:A 5.07 m length of 2.1 mm diameter wire carries 703 mA current when 22.3 mV is applied to its ends. Determine the resistivity of the wire.

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 Use current and voltage to determine resistance. Plug that into the above and solve for ρ. Be sure to change numbers into meters.

Q:i have a black, red, and yellow wires in my trunk for a stereo system.i hear about this remote wire being blue (i have a sub/amp that needs a remote wire, ground, and battery) but i dont know which is which and where to put what.please help

well your battery wire should be at least a 8 guage wire same with the ground. the remote wire should be 18-16gauge

Q:anybody got a diagram or instructions on how to wire an amp wiring kit in a 1999 audi a4

You dont need Instructions for Car Specific. You just Need to Hook the large Power wire for your amp direct to battery, The large black ground wire to the frame or body, Something metal. And the small Power wire To Switched power. IE, a terminal on the fuse block thats only hot with the key ON. Thats it. Good luck.
