Q:Do RCA Cables supply power?
I have not seen or read from any source that RCA cable can be used for power. It is designed for audio connection and video connection only. The wire are not designed for use with electrical power connection, it will over heat and the wires will melt. Hope this will help you out.
Q:IC-2 cable from Power Acoustik?
no offence but its a rip. go to walmart and buy an AUX cable they are 8 bucks and they will fit ipods phones and all that good stuff.
Q:Water and electricity installation drawings in the kz on behalf of what material of the threading tube
No, without this provision, the purpose of blocking the cable piercing is to prevent the outside world on the adverse gas and other reasons of the invasion, in fact, as long as the purpose is achieved, the material selected or look at the situation, such as coal mine perforation must be sealed , The reason is to prevent the wind and air leakage, as well as when the outside world when the explosion of the substation damage, as well as their own substation has a fire source to prevent the development of fire to the outside world
Q:Power cable on outside of garage wall?
If exposed, you must use an armored cable or conduit. No if's, and's, or but's... Personally, I think conduit is your best option.
Q:Can i make a USB cable that has one plug for data and one for power by putting two together?
Yes I'm sure this would work. Just solder the red and black wires to an other usb cable and leave the other 2 data ones going into the computer. Plug the power usb cable into your adaptor and It should work. The device is still getting the 5volts it needs so I see no reason why it shouldn't work.
Q:Is the electricity in a power cable completely lost after unplugging it?
by electricity I assume you mean electrical energy. power is the rate at which electrical energy is consumed. Power is generated by the flow of electrical current across a potential difference. Let's use an analogy. A cable is like a water pipe. Current is like the flow of water in the pipe. Pressure is like potential difference (voltage). When there is a difference in pressure at the two ends of the pipe, water will flow through the pipe. The flow of water carries energy, because it can be used to spin a paddle wheel (motor), and the friction of the water against the pipe (electrical resistance) generates heat. I think your question is something to the effect of, if I suddenly remove the pressure difference across the pipe, won't there still be energy in the water flowing in the pipe, and isn't that energy wasted? Well, there's a difference between water and electrical current: the electron hardly weighs anything. There's very, very little energy stored in the motion of electrons in a wire. When the wire is disconnected, the electrons come to a stop almost immediately, and the amount of energy wasted is infinitesimal. I hope that sort of answers your question.
Q:How much power can I draw from the 12v on the Xbox 360 DVD power cable?
its not smart to attach anything to your 12v power on the dvd line it can cause problems to your 360 and your dvd drive. get your 12v directly from the power socket .
Q:Where do i put the power cable of a video card on the Motherboard?
you take the power from your power supply to give to the video card. older cards use the 4-pin moly connectors and the new ones use either 6-pin or 8-pin PCI-e, If you don't have the right connectors from the PSU then you can buy an adapter for about $4 at most computer stores
Q:What kind of material should be selected for the fixing bracket of the cable trunking
2.5 square copper (green, with the threading tube) theory will be able to withstand about 20A current, consider the pipe, temperature and other factors, so according to the actual can withstand about 3 kilowatts of power. In fact the 2.5MM2 copper wire is generally open 16A can withstand about 3.4 kilowatts of power.
Q:Why does car Audio power cable have such thick insulation?
RCA Cables: These are the cables used to transfer pre-amp (line level) signals. Usually, you use this type of cable for unamplified signals such as the connection between your head unit and amp or crossovers/eqs. Look for appropriate thickness and shielding. The end connectors should be sturdy to prevent breakage from stress. Some claim that very expensive cable makes a difference in sound quality. I do not think so, do not spend more than $1/foot. You may need to spend more to get cables that are more immune to noise if you have that problem in your car
