Q:Ceiling fan has Green, Blue, black and white and the ceiling only has a black wire and white wire.

That fan has separate power leads, either for light/fan, or two speeds. The simplest way is just tie black and blue from the fan to blk from the box, and white to white. The wall switch will control the whole thing, one speed or fan + Lt.s.

Q:The resistivity of a 18.0 m long wire is 3.76E-8 Ω.m and its cross sectional area is 6.52E-6 m2. If the wire carries a current of 1.44 A, what is the voltage across the wire?

R = ( rho x l)/A Where: R is the resistance, rho the resistivity, l the length and A the area Resiatance of wire = (3.76 x 10^-8 x 18)/6.52 x 10^-6 R = 0.1038 Ohms Voltage across wire = current through wire x resistance of wire V = I x R V = 1.44 x 0.1038 V = 0.14947 V = 0.15 Volts

Q:I recently took out my old ceiling fan, and now there is a Black, Red, And White Wire hanging from the ceiling, I bought a track light that has a box with a Green, White, and Black wire in it. Which wires am i supposed to connect,It's for the light Switch, and I'm not sure when the house was built, its a Reading, PA Row house.

It looks like you had a fan and a light, with separate wall switch controls. The black was the fan and the red was the light (or vice versa) and the neutral for both. Connect the black to black, white to white and cap off the red one and turn on the switch. If the light doesn't work, switch it off again (at the breaker, silly), connect the red ceiling wire to the black wire of the light, cap off the ceiling black wire and try again.

Q:Well I have a mono D and it has - - + + on it and I want to to wire my dvc 4ohm sub to 2 ohms but I'm not sure what terminals I hook the speaker wire up to?

wire okorder /... and than wire it to any of the negatives on the amp its all one channel internally so it really doesn't matter which negative u use. than wire the positive to any positive on the amp.

Q:Hello,I got a ventilation fan for the bathroom. The fan has 2 wires and there are 2 wires sticking out of the wall.How do I know which wire connects to which wire?What would happen if I connect the wrong wires?

It's usually color coordinated like white to white and black to black but if you really want to be safe check your wires with a tester and go from there.

Q:me and my friend were doing a circuit challenge and we did the same circuit but she used thicker wires. does it make a difference?

It depends on what the resistance of the rest of the circuit was. The resistance of relatively short lengths of really thin wire would be less than 2 ohms, probably less than 1 ohm. Thicker wire would be maybe 1/4 ohm. So only if the circuit's components were in the neighborhood of 25 ohms or less, would the difference in thin and thick wires have a real significant affect on the circuit.

Q:I have a wire coming up from my basement that has 3 wires (red, green and yellow). I want to connect cat5 wire to that (twisting the wires together) and run the cat5 to an RJ45 box. What's my diagram going to look like?

Cat5 requires 4 wires (two pairs) - you cannot use old telephone wire. second, if the old phone was was 2 pair, you still could not use it. Cat5 is good to just over 300MHz. The old voice grade JK cable could not transfer data very fast. Just use the old phone wire as a pull. Connect a new run of Cat6 to the old wire and pull the new wire into place using the old wire as a pull string.

Q:just bought a brinks indoor motion sensor switch and having problems installing. the regular light switch has 2 black wires that was connected to one end and a red to the other. the white wires in the wall are already together. the motion sensor switch has black, blue, red wires and its ground wire. the instructions says not to use the red wire for single switch so confused on how to wire them.

There should not be a independent conductor on the change; or, are you checking this for the circuit on the panelboard? Or, do you propose you're analyzing 40 5 Volts between the ungrounded (warm) conductor and the change-leg? you ought to no longer get any modern analyzing from the change-leg whilst the change is opened. If there is modern modern, the change is undesirable. in case you have become a analyzing between the independent (the grounded conductor) and floor on the easy container, that must be the consequence of a multi-twine community, the place the independent is shared between 2 opposite circuits. The independent will carry any unbalanced load between the two circuits. because of fact of this you ought to by no potential assume the independent no longer wearing any modern circulate. attempt changing the change. purchase one that doesn't grant any lower back-stab connections, as they are additionally the source of many issues. If the priority extends previous that, my suggestion, as continuously, is to call a qualified, authorized electrician.

Q:I recently Hooked a newer Pioneer cd player up in my 00 mustang gt!.. it will not keep memory. The only way it will come on is when the red(power) is hooked up with the Yellow wire!.. but this way it will not hold a memory.. theres a few orange wires but i have hooked them up and it still wont keep memory? any suggestions?

When wiring the Red and Yellow together, the radio will have constant power to it at all times. Try to rewire it so they aren't wired together so it doesn't keep on at all times, and as far as the memory issue, I suggest calling Pioneer, there could be a problem with the actual head unit.

Q:I'm faced with a dilemma...I'm wiring my basement right now and all is fine, except for my living room. I want to have a 3-way switch setup, but with four light fixtures. I've already ran 3+ground wires in this order...Breaker box - Switch A - Fixture 1 - Fix. 2 - Fix. 3 - Fix. 4 - Switch B. I have done regular 3-way switches in the past, without much trouble, but I have no idea how to wire this, so well-explained instructions would be perfect.Thanks so much!

A normal three way has two wires switch to switch and one wire from each switch to the single light. All you have to do is wire the lights in parallel, Each wire will go to one side of all three lights. The light to light wiring is no different then any other multiple light on one switch wiring. Except in this situation the two wires are coming from two different switches.
