Q:at least 3 examples for wire and wireless......

Wire simplex: Serial data from GPS to PC or autopilot using 2 wires. Wire, half duplex: Theatrical intercom, with push to talk buttons for each spotlight operator. Wire, full duplex: telephone. Wireless, simplex: infrared remote control for TV. Wireless, half duplex: walkie-talkie, family radio service, cb radio. Wireless, full duplex cellphone, cordless phone.

Q:Okay so bought 2 Kicker Comp C12-8 subs they are single voice coil, and I bought the Kicker DX300.2 amp. I would like to parallel wire thes subs to have a 4 ohm load, But I don't totally get the concept of it. Could somebody explain it, or show me a diagram, or video, or something?

Parallel: okorder /

Q:I have eight speaker wires, I can figure that out on my own. I also have a red/blue stripe, black/red stripe, black/white stripe, and blue. Which ones are the power wires?

you will need a DVM, to find what is what. Check the fuse box, and make sure the fuse is good, and search for the constant power.Set the meter to 20V. I like to stick the ground on my meter, in the ignition where the key goes. Then find the switched, key on wire. obviously, you'll have to move the ground on the meter for that. Don't forget to solder and use heat shrink tubing, or red and blue butt connectors, and heat shrink, or tape them well. Then set the meter to ohms, or the omega pic on the meter. once you find a resistance for each speaker, pop it with a 9V battery, not a AA, as both terminals are on top. then when you hear which speaker pops, wire it accordingly. Good Luck!

Q:A wire is 1.5 m long and has a diameter of 1.5 mm. The stretch modulus of the wire is 6.2 x 10^10 N/m^2. If a force of 400 N is applied to end of the wire then the increase in length of the wire is???please help, thanks

The stretching of wire by longitudinal force: If F force applied across the crosectional area A of wire of radius r and lenght L then the wire elaogates in the dirextion of force Stress P = F / A A = pi* r^2 = (1.5/2)*10^-3 = 7.5 *10^-4 m^2 strain produced = dL / L = increase in length / original L Young's modulus or elastic (stretch) modulus for the maretial, within elastic limits, Y = stress/strain strain = stress / Y dL = F * L / A * Y = F * L / pi (r^2) * Y dL = 400* 1.5 / 3.14 (7.5 *10^-4)^2 * 6.2*10^10) meter dL = 0.005479 * meter dL = 5.479 millimeters increase in length

Q:i have 4 wires going to a ac unit #10 wires 2 wires for each cir. and i need to know how many amps can I run with 2 #10 copper for one side of the breaker

10 gauge wire is rated for 30 amps unless its a long run. I'm not sure I'm picturing the right setup you're proposing in your description but if you're talking about having two 'hot' wires and two 'neutral wires' clamped together at both ends its a bad idea. It would make sense that you could run 60 amps through the wire if it was doubled up like that but because of [science] it doesn't work like that. Not to mention any electrician or inspector would be drawing exclamation points on their notepad if they saw a setup like that. If you need to run more than 30 amps just buy lower gauge wire.

Q:the wires are all cut off. which 2 do i connect and which is which and what is what?

Starting with the Instrument panel fuse 20amp, wire is yellow (+) coming from fuse block to the cigarette lighter. Coming out of the lighter is the black (-). If you have a test light find the yellow wire, turn the ignition on to accessories and with the test light grounded the light should come on. Then find the black wire connect the two. If you still can’t get it you can run a 12 gauge wire from the cigarette lighter fuse and then run a separate 12 gauge wire to a good ground on the car. If you are messing with live wires try not to let them arc. If your not getting any power check your fuses. Or don’t smoke.

Q:How to connect a 5 wire Harley LED tail light

The 5 wires to hook up the tail light and directionals. The tail light should take 3 wires. There should be a common ground which is the black / white wire. The white/ black wire and the brown wire are for the tail light(BR) and brake light (W/B). Easieset way is to take a test light to each of the wires. turn the ignition on, connect the test light to the wires one at a time. There should only be one wire that lights (tail light) then press the brake, there are two of those that should come on. Your original had two white/black wires because there were two bulbs in the original tail light. I would just use one white/black and cap the other one. Hook two to the tail light (W/B, Br) plus the black / white wire to ground of your new light. Then turn on one directional and there should be one that blinks with the test light and then the same for the other directional. wire one each to left and right plus to the black/white wire if each directional requires the ground.

Q:When was the hot-wire anemometer invented? and who was it?

Who Invented Anemometer

Q:I just bought an aftermarket cd player for my Grand Cherokee and I would rather not have to cut and strip wires so I want to get an wiring harness adapter. My question is, can I just get any wiring harness adapter or do I need the direct connection adapter that is specifically made for Chrysler to Kenwood?

Doug is spot on, but missing one thing that im going to add in real quick. The wiring harness makes things simper because it is color coordinated with the aftermarket wire radios. Some chrystler/dodge/jeep come with an existing amplifier that must be bypassed in order to have sound come through the speakers. Lucky this bypass is easy as connecting a wire. (quick note, buy only metra install kits- wiring harness and dash kit) On the wiring harness there will be a blue wire (not to get confused with the blue wire from the radio) coming off of it. This needs to be hooked up with the red wires, or the blue wire from the radio's wiring harness which is the amp remote wire. This bypasses the amp.

Q:Live wire- bring current to appliancesNeutral wire- returns the current from the applianceMy question is, if we are using AC current, then in the next half cycle, the live wire will return the current from the appliance and the neutral wire will bring current to appliances. Am I right? If I’m right, then both wires have the same function why give them different names? Really appreciate your help.

You are right technically. However, with AC, the convention is that the current always flows from the hot to the neutral. Yes, we know it reverses every half cycle, but for the convention, just consider it always flowing from the hot to neutral. The difference between the two wires is that the neutral is at ground potential, or within a few volts of it, whereas the hot is 120 or 240 volts away from ground. Another example, a 240 volts split phase power to an electric oven. In this case, there are two hot wires, each at a potential of 120 volts from ground or neutral, but opposite in phase, so the current flows from one hot to the other hot. Again, it reverses twice per cycle.
