Q:What's the difference between stainless steel wire and steel wire?

Stainless steel wire has 304, 316, steel wire does not have 304 and 316 material. Stainless steel wire is generally not galvanized. The wire is long enough to rust.

Q:installing ceiling fan, when remove light fixture, it has 4 wires system, wires used: white red and green with one light switch, what is black for, it has a wire nut, but has nothing connect to it

Look in the box where the switch is installed. Is there a black wire that also has a wire nut on it? If so, someone used a little forethought when they ran the wires to this switch. You will connect one of the wires (red or black, doesn't matter which) to the black wire of the fan, and the other goes to the blue wire of the light kit on the fan. Then connect the white to white, and the ground wire goes to the mounting bracket or bare copper wire of the fan. At the switch box, you will need to add another switch for the fan. If there is only room for 1 switch, you can buy a combination fan/light switch that fits in the space of 1 switch, but has controls for both the fan and the light. Hope this helps.

Q:Im cleaning up some of the wires in the engine bay and getting rid of ones i dont use. Right now theresthe pos side bat post runs down to the starter. From the starter there is a thicker wire and a skinny wire. In the thicker wire there is a wire that goes to the post on alternator. Both wires from starter run over to a relay maybe ithas a stud sticking out and has a wire that goes from the bottom of it to the fuse box. Im in middle of relocating the battery into the trunk so what wires can i eliminate and what wires have to go,to the battery?

Like Mikey reported for starter and alternator it is not appropriate. in case you think of issues have been swapped there are various strategies over the 40+ years that Chev made the classic small block. Assuming that's a Chev motor there are in basic terms 2 starters and the version is the place the mounting bolts are. One version the bolts are in the present day for the time of from one yet another and the different form they're offset. most of the engine blocks have the two contraptions of holes so it relies upon on the flywheel which one is needed. Alternator could be slightly extra challenging to verify. countless strategies will bodily in superb condition then you definately've the pulley form, connector type and charm and orientation. you will be able to ought to snap some pictures and desire for an surprising guy on the aspects save or carry the previous one in and tournament it up.

Q:ok...all the wires in my quot;atticare encased in this silver metal casing....when i opened a bathroom wall...the wires were also like that.....at the fuse box...they all leave like that........sooooo, can i assume all my wires are encased like that? does that make them pretty safe from rodents chewing? (yup-been watching Billy the Exterminator) why were they done like that? tx for any info....

In the U.S. it WAS called BX and is now called MC, standing for metallic clad. (If the lines are flex-able). This stuff was used to protect from damage. This is usually used in commercial applications, but is perfectly legal (if the proper connectors were used) in residential applications. It sounds like you are doing a remodel. If so, you will need a EXPERIENCED electrician to modify the runs for you. Don't let anyone tell you it is against code. It is simply overkill.

Q:if a wire of initial length, and radius has a measured resistance of 1.0 ohms. the wire is drawn under tensile stress to a new uniform radius of 0.25r. what is the new resistance of the wire?

Wire resistance =( length/area) x a constant When drawn, the wire radius is 1/4 of original, and it's length is 16 times of original (because volume is unchanged). Solve for new resistance/

Q:currently I have 2 12woofers wired to a single amp with 2 gauge wiring. Will it make a noticable difference if I upgrade the wiring to 0 gauge?

you can try Rockford Fosgate web site for wire calculation. just enter your best guess.

Q:im trying to install a cd player i need to know where i can hook up power(red) , constant(yellow), and my amp seems to take alot for remote wire so i need a good source for it too i also have a eq to power but dont know if it will work with the same source as the radio

Before you go through the painful task of rewiring all your speakers, don't. Go to a stereo shop and purchase the amp bypass plug that is available for your Explorer. It will plug into the 2 plugs you pulled out of the factory amp which will allow you to connect your radio to the factory harness in the dash as normal. You also want to use the proper adapter harness in the dash for that. It will be color coded to the aftermarket radio so there will be no question as to which wire goes where. The red and yellow wires on the unit will go to the red and yellow wires on the harness.

Q:What are the basic characteristics of wire resistance strain gages?

The resistance value of the components size and temperature, material, length and cross-sectional area, the measure of the size of the resistance is affected by temperature is the temperature coefficient of resistance value, which is defined as the percentage change in temperature rise every 1 degrees. The main physical characteristic of resistance is that the electric energy is heat, and it is also a component of energy dissipation. Resistance usually acts as a divider and shunt in a circuit. For signals, AC and DC signals can be passed through resistors.

Q:i want to rewire my trailer harness on my truck. i have a 6 wire roung plug but i wat a 7 wire plug. what is the 7 wires for?

Don't know where the hell you got a SIX wire plug from? Standard plugs are usually 5 or 7 pin. However, to answer your question, providing that you use the same color codes as we do, yellow is for the left turn signal, green the right. White is the earth, red for brake lights, brown for tail lights, and black for reversing lights (if fitted). That leaves the blue one as a spare which can be used to power an interior/ exterior work light on the trailer. In Australia and NZ we only have the 5 or 7 pin plugs. They are made by either HELLA or NARVA and each companies male/female plugs are compatible with each other. Google either company and see what is available. Hope this helps. P.S. For the cost of a return airfare and cigarettes, I am willing to come over and wire your truck and trailer for you AND I'll bring a set of plugs for free.

Q:i need magnetic wire to make a coil and build aradio

You can often get varnished wire at an outlet such as radio shack. I have also used the yokes of old TV sets that I usually got for free at a local repair shop. I had to carefully unwind the coils. The wire in an automobile ignition coil is another potentially free source. You can purchase electrical insulating varnish as well. Krylon makes an aerosol variety and most others come in a regular can, but you would have to be creative in dipping the wire and suspending it to dry without damaging the coating.
