Q:I've had my subs wired up for a while but want to see if there is a more efficient way to do it. Hardware: Sony Xplod 800w amp bridgeable amp - What's the best way to wire these up to get the most volume?

wire the voice coils to series on each sub and then wire the subs in parallel to the amp and voila.

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?

assume the volume of the wire is constant cross sectional area = pi*R^2 A1 = PI * r^2 A2= PI * (.25*r)^2 = PI * .0625*(r)^2 = 16* A2 If volume stays constant, Length2 = 16* Length1 since resistance is proportional to length/area R2/R1= L2L1*A1/A2=16*16 = 256 The resistance now 256 times as great

Q:A vertical straight wire carrying an upward 14.2 A current exerts an attractive force per unit length of 7.80E-4 N/m on a second parallel wire 7.60 cm away. What is the magnitude of the current that flows in the second wire?

For a current I1 = 14.2 Amperes and radial separation between wires r =0.076 m, the magnetic field at wire 2 is B =0.000037368 Tesla If current I2 = 21 Amperes then the force per meter is F/ΔL =0.000784 Newtons/m hyperphysics.phy-astr.gsu.edu/hba... Goodbye

Q:i got a fi bl 15dual 2 subwoofer. im wiring it down to 1 ohm.now for the problem. lets say im wiring the positive terminals together. am i suppose to wire it all with positive wire or can i also use negative copper wire? i used two positive wires and one negative wire to hook up the three positive terminals. is this bad? do i need to make all of them positive silver wires?

ok well either red or + is positive and black or - is negitive, the problem i have is you said you had 3 positives and one negitive on a dual coil sub,?? if you mean you ran all 3 wires to your amp then its wrong, if you mean you ran 1 wire to your positive,1 wire to your negative, and 1 wire from the other positive and negative together, then you have gone up to 4ohm and not down to 1, you should have 2 positives and 2 negatives, hooked together to make 1 positive and 1 negative as for the wire colors, they sometimes differ so you can tell them apart, providing your the one who screwed them to the amp, i run mine copper positive and silver negative, but each to there own.

Q:what if I use a 100 amps.main braker to wire my range and dryer

Whoa there! What you're describing is a 120 volt outlet (U.S. Canada). Every dryer I know of operates from 220 volts. For a three-prong, 220 volt plug, you should connect the black to one of the hot terminals and the red wire to the other hot terminal. The white wire, which is neutral, would go to the common terminal. The outlet box you describe is a 120 volt box. . .it just won't work! If you're operating a 220 volt dryer from 120 volts, you're asking for trouble. Besides, for a 120 volt outlet, you've got the connections all skewed. Here it is as looking at the outlet from the front: Black (hot) to small blade (brass screw), White (neutral) to large blade (silver screw), Copper (ground) to green grounding screw. You may have to run a 220 volt line from the dryer to a new breaker in your electrical service panel. I strongly suggest you leave this to a licensed, qualified electrician.

Q:I'm replacing the ground wire in a chandelier because it has been cut by the previous owner when it was removed from the ceiling. Overall it is pretty simple and I have everything diagramed. When I went to Radio Shack and bought the replacement wire they gave me 18 gauge solid insulated hookup wire. It looks totally different. The ground wire is a braided copper wire (7 strands). Should I go back and take my copper wire with me and get copper or is what I have just as good? An electrician will do the installation of the chandelier into the ceiling.

Radio Shack's hookup wire is copper, but it may be tinned so it has a silver/chrome color instead of a copper color. Tinned wire is more expensive but is also more resistant to corrosion. Braided wire is more flexible than solid wire, but either will do the job. The only real important consideration is the gauge of the wire. You want to make sure your new ground wire is at least as thick as the old one.

Q:the sensor part has 4 wires,(2 white,1 black and 1 red)each light has 1bl.and 1white

Wiring a Motion Sensor to an Existing Security Light: Materials (5) Wire Nuts (Yellow) Electrical Tape Screwdriver Directions 1. TURN OFF POWER TO FIXTURE! 2. Remove light from base to get to wiring. 3. Remove wire nuts from existing black and white wires. 4. Connect white wires togeather with wire nut. 5. Connect red wire from motion sensor to black wire from lights. 6. Connect black wire from motion sensor to black wire from power source. 7. Replace fixture to base. 8. Turn power back on. Hope this helps.

Q:Can I run a 10 gauge 2 wire plus ground from a double pole 30 amp breaker to a dryer that uses 240v? I need to know if the one black wire will be sufficient or if i need to get a 2 hot one neutral wire.

No you need two hot and a neutral your element needs 240 volts.

Q:I have 2 wires that go from the Solenoid to the wiring harness. But i don't know which wires go to where. One of the wires from the Solenoid it the remote switch and the other is the power for my whole interior. There are red, orange and black wires that come from the wiring harness. but i don't know which ones to use.

Your looking for a drive ,but if you would like to look for a starter try Competition Sales online.They deal with mostly Chevy performance parts. Good luck

Q:While updating the parents basement we needed to replace a very very old 3 way switch. However, the wiring to the Fluorescents seems extreme to me. Here is how i can describle the layout. Panel - junction box - double splice (one to light fixture and one to threeway switch below it)-. From that threeway switch 12-3 wiring to upstairs landing with other threeway switch resides. How should I make my connections to switches? If the other swtiches were not so old I would just copy them.

A hot wire from the panel to the first three way switch on the common screw. Two runner wires between the two switches on the other two screws. A wire from the common screw on the second switch to the hot wire on the light fixtures. A neutral wire to the light fixtures from the panel. Look at Bert's pictures.
