Q:Several colors of the power line represent how much voltage the voltage is

Hello there! According to the problem you are connected to the positive (generator! Fuse box! Ignition switch lights)! The negative pole is connected to the engine body! On the body! Chassis! Hope to help you [car problem, ask the car master. 4S shop professional technician, 10 minutes to solve. To

Q:Why should the wooden pole be burned and buried again?

Attenuation is too large, it is recommended to buy a general but can be used. Wireless card generally does not exceed 3m line.

Q:I know that electrical resistance will decrease if you increase the cross-sectional area of the wirebut if that's the case, then why aren't wires made larger?? There must be some reason, some con to increasing the 'A'? I haven't touched Physics since high school, so I really don't remember. Thanks.

The only exception to the excellent answers that have already been provided is in the case of radio-frequency (R.F.) currents. R.F currents are caused to 'crowd out' to the surface of the conductor. Consequently, the R.F. resistance of a conductor can be many, many times that of its d.c. resistance. There are two classic methods to combat this (undesirable) effect. One is to use Litz wire (look it up on the 'Net); the other is to use wire that is much thicker than what is required for the d.c. current that it passes, but the increased diameter of the wire produces a larger surface area - which is usually silver-plated, to reduce the R.F. resistance even further. Litz wire is usually used in the frequency range 100 kHz to 2 MHz; the silver-plating method is usually used in the frequency range 50 to 1000 MHz. .

Q:I have replaced phone chargers, computer parts,speakers, etc. Sprays don't help, I have tied up the wires, bagged them, put them out of her reach. I can't catch her doing it to spray her with water. I am getting angry, going broke and love my cat too much to get rid of her.

Get one of those cheap water guns and squirt the neck and tell them NO in firm but not to loud voice they should stop. P.S. make sure the gun is not to high in power spray bottles work well also.

Q:Wire yellow and green, respectively, that line of fire or zero line

Third, in the cable trench, tunnel, when both sides of the cable bracket, 1000 volts below the power cable and control cables should be as much as 1000 volts and above the power cables were laid on different stents Fourth, the height of the cable tunnel is generally 19 meters; difficulties, in the local area may be appropriate to reduce the length of the cable bracket in the cable trench should not be greater than 350 mm; in the tunnel should not be greater than 500 mm cable in the cable trench, tunnel laying when the net distance, should not be less than the specified value Cable trenches and wire tunnels should be waterproof; the slope of the bottom drains should not be less than O 5%, and should be set water puddle; water can be collected by the puddle pump, when the conditions, the water can be directly discharged into the sewer

Q:Hi,If you were to wire up this motor, how do you go about doing that? To connect it to the mains for example.

There are 5 or 6 11966 motors ranging from 1.5VDC, 1 Watt to 12VDC 20 Watts. These motors are normally powered by flashlight (torch) cells and not 220VAC. Adapters and approved, rectifying power supplies are probably available from the same source. You can wire these motors any way you wish if you confine yourself to flashlight cells, and approved power supplies.

Q:I would like to wire two wall sconces on either side of my fireplace. I was planning on continuing the electrical circuit from a wall outlet located near the fireplace and including an inline switch. The outlet is on the left side of the fireplace so I was planning on running the wire 6 feet strait up from the outlet, over three feet, installing a new electrical box and mounting the sconce. The question I have is, how can I run the wire to the other sconce on the right side of the fireplace. Can I run the wire in the wall in front of the fireplace? Also is there any electrical codes that require switches to be a certain height off the floor? I live in southern California.

Usually only one outlet is controlled by the switch. But check it out by plugging the lamp into both. If only one is indeed coltrolled by the switch you need to shut odd the power at the breaker panel, remove the cover plate and the outlet from the box. there's a screw on each side of the outlet for each plug. loosen the screws, make a bend in the wires, hook the wires on the screws and re tighten them, teassemble and turn the breaker back on. Try the light.

Q:I'am going to put in baseboard heat in my basement,the unit I want to put in is 240 volts 1000 watts, what size wire should I use or can I run 2 12-2 lines from 2 differnt lines?

As someone else said. You only need one 12-2 wire. You could run it on a 15 amp double pole breaker. Just Use the black and the white as hot. Connect the black to one pole and the white to the other.

Q:Ten five hundred twenty two, five five five four three circles, seeking to explain more specific meaning

ZR is a flame-retardant letter representation, flame retardant can be divided into A, B, C, D four grades, A flame retardant performance of the highest, followed by decreasing, national wire and cable industry standard (GB) requirements to C level

Q:What is the meaning of the national standard BVR?

Therefore, when the cables are running at the time of power supply, the two power cables are basically close to each other and the distribution of the current is basically uniform Too heavy, ahead of a large area of ??fever burning phenomenon 3 Parallel operation of the cable, the distance between each other to consider the appropriate amplification, so that when a cable failure, it will not affect the parallel use of the cable at the same time burned, which to a certain extent, reduce the power of economic losses The 4 Parallel operation of the power cable, the cable at both ends of the nose and the switch contact with the contact state, regular checks to ensure that the cable and switch connection is good, because the parallel use of the cable mostly in 35mm2 above the conductor resistance per kilometer in the zero Ohm below, the resistance of the order of magnitude in the 10-1 or so, if the cable nose and switch contact is not good, it is easy to lead to a switch at the cable of a phase or a few phase contact resistance is too large, resulting in two cable carrying capacity allocation is not Uniform, and now the cable customers to take into account the economy and power grid design, cable model specifications will not leave too much capacity of the remaining capacity, when the line nose contact resistance is too large, one is the continuous use of the fever burned Off, and that is caused by two cable carrying capacity shift, resulting in one of the cable overheating burned 5 Multi-core armored power cable in parallel use in the AC power grid, each cable must be A phase, B phase, C phase alone out, respectively, with the switch A, B, C three-phase, Connect all the cores of a cable to a phase of the switch
