Q:Which of the following wires would tend to have the least amount of electrical resistance? a) long b) fiberglass c) hot d) thick

Resistance = (Rho x L) / A Resistance = Resistivity (a number determining how well a material conducts electricity) x L (length) / A (Cross sectional area) That the material with the least resistivity, and the shortest length, with the largest cross sectional area, will have the least resistance..

Q:my light stopped working ( a chandalier ). It has brown wires, blue wires, red wires, beige wires, and white wires.

How many lamps (bulbs) does it have? Larger chandeliers are capable of being switched on/off in layers (so you might have 3 switches for a 12-lamp fitting) All you can do is trace the coloured wires to each lampholder to ID live/neutrals (Multimeter with power OFF)

Q:i bought a programmable thermostat, and the wiring i see doesn't make any sense. it's for central air, heating and cooling. there are no tags or labels on the wires, and it was probably installed in the seventies.there are four wires coming out of the wall, and they're screwed into four of six slots:Y = blue wireG = red wireW = green wireR = white wireB = emptyO = emptythe new thermostat has the following slots: G, Rc, Rh, Y/O, W/B, Y1. how should the old labels correspond to the new ones?

First of all from what you are saying on how the old thermostat is wired,your furnace is wired up wrong...On the old thermostat the red wire should go to R... The white wire should go to W... The green wire should go to G... And the blue wire should go to Y... On the new thermostat the red wire should go to Rc and a jumper wire from Rc to Rh... The white wire goes to W/B... The green wire goes to G... and the blue wire goes to Y1... But if your sure that your old thermostat was wired the way you say it was then the red wire goes to G...the white wire goes to Rc with a jumper wire to Rh... the green wire goes to W/B... and the blue wire goes to Y1...

Q:Which wire is quot;hot, white or black?

Black is hot in AC voltage white is your neutral

Q:what wires connect from the vehicle to the a/f sensor

Why do u want to know what wires go to the sensor? If you have a code for the a/f sensor..99 % of the time it is an open in the sensor itself. On rare occasion there are others like a chewed wire by a rodent. But I would just recommend replacing the a/f sensor. And i u were to follow the wires from the male connector they would lead you to a big wire harness that basically just all ends up at the ECU. Just in case u wanted to know.

Q:My starter I replaced has 3 wires, two red and one black. Where does each wire go? Pictures would be very helpful if possible

based upon the gauge you have... i do no longer think of you're placing it to a mustang yet i detect genuine low-priced air stress gauges are very deceptive.. your 5.0 may well be 50 psi (if it relatively is prolonged each and every of how out) and is a great way overinflated. the properly suited tire stress is the two interior the glove container on a plaque interior the door or is a sitcker on the rear door section.. yet stress could desire to be form of 32 psi (220 kps for our metric friends) on your motor vehicle in case you haven't any longer pushed it for greater effective than 8 hours...

Q:i am hooking up a wiring harness on a 2000 ford ranger and cant figure out the wires to hook up and what they are

Generaly speaking: Red = Right turn Yellow = left turn White = ground Blue = running/parking lights brown = electric brakes Most trailer sales places can sell you a simple adapter that sipmply plugs into your truck wires behind the bumper.

Q:But I want to switch it and wire the red ceiling wire to the black fan wire and the black ceiling wire to the black/white fan wire so that the particular switches work the way I want them to. Is this ok, to switch them?

Black wire on the fan is for the fan motor, red wire in the fan is for the light, the white wire is the neutral wire. So if you do want to switch the light off and on you have to tie red wire to the switch and the black wire can be tied to the hot at the ceiling box so you can control the fan with the chain only. If you have one switch leg in your circuit then you cannot do anything but switch them both if you tie them together. I think I am understanding what you are saying here. White Alyse ties to white Black is for the fan motor and the red is for the light. If you have three wires in the switch then you can tie them the same way color to color. Hope this has not confused you You can email me if you need further help

Q:hi can anyone help i am currently building a 50cc scooter up from scratch i have most parts but ive started on the wiring does anyone know where i can get a wiring diagram also what wire recharges the battery from the magnetic pickup thanks

Q:I Have a 02 Dodge ram with the 5.9L engine and i purchased a O2 simulator because i wanted to remove the cats. what i need to know is which wire is the Signal, 12 volt, and the ground wire on the oxygen sensor. If anyone has any idea please share some info.

The wires should be color coated. Usually if it is a 4 wire o2 there are two white wires and two black wires and the blacks are both grounds. Same should go with the 2 wire o2 the black is usually the ground and the wite is the 12v wire.
