Q:can you use your existing phone line jacks and wire, then convert the jacks to lan to network computers or printers?

No, you cannot use a phone line wire for LAN. The wires and jacks are different. Lan cables (cat5) have more wires inside than phone line cables which only have either 2 or 4 wires. If you need a LAN cable, you'll have to go out and buy one.

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

correct.....both can be hot, as they may have been cris crossed from point to point. the best is to get a volt meter and test to your water pipe if its grounded and not eroded away over the years. problem with using an inductance tester is it may give an erroneous reading if they have been cris crossed. note.....once you find the hot of the two, the other bing the neitral will have a current on it that can be fatal, remember there is no ground to protect you, and if your in water or touching something metallic, you may be the ground path needed to complete the circuit. be careful!

Q:how do i wire a dual 2 ohm sub to an amp at 2 ohm

You can't. Dual 2 ohm subs can only be wired at 1 ohm or 4 ohm. To run an amp at a 2 ohm load you need a dual 4 ohm sub. You can get a second dual 2 ohm sub to match and then they can be wired together at a 2 ohm load.

Q:i have my wires installed by a professional, and i wanted to put an taco switch to run to my amp, if i run a taco switch will it be okay? and with messing up the wires that he already ran would it screw it up?

why do you need a taco switch on the amp. im assuming that the amp stays on 24/7, if it dues that was not a professional that did the install, you need to connect the ( remote wire) from the head unit to the terminal on the amp (-B)

Q:why use a large gauge spark plug wires

What is High Tension Electricity? In all my engineering classes, never heard of it. I wouldn't use large gauge spark plugs unless they were specified. If you use them and they're not specified, you could ruin the spark plugs for too much voltage.

Q:We added an AC to a preexisting sx 80 furnace and we are having a hard time wiring the new thermostat to the furnace, and the condensor to the furnace. Anyone know how to get a wiring diagram?? thanks

i could yet I certainly have some project's ! I Dont like your stance on Banning Cucumbers , nor do I know it !! What did they ever do to you ! heavily What could you do for a Klondike Bar ?! Get Tortured ..... LOL Oh and # 3 , properly that solves taking away the Senior electorate on the line ! Hmmm heavily Smallville what could CK have left to do Farm artwork( properly if doing it shirtless it would not be uninteresting ) ! I do like # 7 ! # 8 would not sound undesirable ! I imply truly what do they want all that money for in any case ! # 9 sounds good , i've got faith there are some extraterrestrial beings hiding in my associates Basement yet i want greater examine ! # 10 i do no longer desire to Punch them i want Fist Pump with them and get inebriated and then flow out to consume with them ! after shall we flow decrease back to there homestead and make exciting of the Grenades and communicate in regards to the lovable Guido's we'd desire to Smush ! different than for that I certainly have an argument with calling you King Pigtails once you look like Cindy Brady ! Thats purely incorrect !

Q:two straight and parallel wires are separated by 6 cm. there is a 2 A current flowing in the first wire. if the magnetic field strength is found to be zero between the two wires at a distance of 2.2 cm from the first wire, what is the magnitude and direction of the current in the second wire?

If the magnetic field at 2.2cm is zero it means that at that distance the fields produced by the two wires cancel out. At 2.2cm from the first wire the field strength is B= uI/ 2pi r ... . where u is the permitivity of free space, 4.0 x 10^-7 N/A^2 B= (4.0 x 10^-7 N/A^2)( 2 A)/ 2(3.14)(0.022m) B=( 8 x10^-7)/(0.138) B= 5.79 x 10^-6 Tesla The magnitude of the magnetic field from the other wire must be equal in magnitude at 3.8cm away (6- 2.2) and opposite in direction. Using the right hand rule (thumb points in direction of current and fingers curl around the wire to show the direction of the magnetic field) you can see that for the magnetic fields to be in opposite direction between the two wires the current must be flowing in the same direction as the first wire. Using the formula for magnetic field strength you can then determine the current needed. 5.79 x10^-6 T= (4.0 x 10^-7) I/ 2 (3.14)(0.038m) THen solve for I I= (5.79 x 10^-6 T)(2)(3.14)(0.038m)/ 4.0 x 10^-7) I= 3.45 A Therefore there is a current of 3.45A in the wire and it is flowing in the same direction as the first.

Q:when installing two subwoofers to an amp, can just normal speaker wires work or do I need any special wires to hook the subs to the amp?

speaker wires will do just fine

Q:like can u use home power wire that is 4 gauge rather then getting the car power wire

Home okorder /... (spanky, well trying to run solid wire in a car would be a real task! lol) And, 4 gauge can handle more than 95 amps.

Q:Hi there,I have a very old house which only has 2 wires (1 white, 1 black) coming out of the wall.The ceiling fan / light has 2 red wires, 1 black, 1 green.What is right way to wire for this to operate?Thanks,

Most fans have a wiring schematic and this will tell you how to wire it. Normally black is the power, green is a ground, which you don't have, and as for the red wires I'm not sure. Is this a new fan or one that has been used before. In the USA we have a white wire which is a neutral. I'm puzzled about the two red wires, these may have been added at a later date. If your in a country that has 240 volts then this may be an explanation. Regards, Dale
