Q:Cable bttz-4 * (1 * 50) and bttz-4 * 50 What is the difference: To use the video card at the same time connected to the computer monitor and TV show together, have to do the following: 1) graphics card must include HDMI, including two or more signal output interface. (Such as the shadow GTX650 there are DVI, VGA, HDMI three signal output interface.) As long as the graphics card to meet this requirement, no matter which brand can be. 2) graphics card HDMI interface has to support the original sound decoding, that is to say with the HDMI cable and TV connection will have a sound output. 3) in the TV or computer monitor line to use straight, can not transfer. Because a card when the transfer may not show. 4) After installing, enter the display adapter from the Start menu. The contrast display to set, to show the same content to select the copy; to display different content on the choice of expansion on it.

Q:if i remove the power cable and switch on it works normally without restarting , plz help with this ~?: go in control panel and set ur laptop settings to not to start while swith in

Q:The power supply I have has 8 Peripheral cables. I need just a few more than that. Is there a cable splitter I can get? Or what can I do? I have the power, just need the extra connectors.: Yes, splitters are available. But when you say you have the power, that is not the full requirement. Each segment of the power supply out (called a rail) has a limit. Too much draw on any single one will lead to device problems or even a failure in the power supply.

Q:Power cable yjv22-10kv-3 * 50 what it means: Yj is cross-linked polyethylene insulation, v PVC sheathed 22 is double steel tape armored, voltage 10KV, 50 square three-core copper cable

Q:(for example : 1sqmm, 4sqmm, 35 sqmm) i need a formula to calculate current by knowing the area of the cable?: This is not a simple answer. The amount of current that a cable can carry depends on the amount of voltage drop that you can tolerate (mostly an issue in long cables) and the temperature rating of the insulation used on the cable ( the higher the temperature rating, the higher the current that you can run in the cable) and the ability of the cable to loose the heat that is generated from the I^2R drop in the cable. For example, if a cable is in open air with no other heat sources near it, it can accomodate more current before compromising the insulation. If a cable is in a conduit with other cables that are generating heat, then the conductor needs to be increased in size to decrease the heat. The ampacity of the cable is also affected by the duty cycle of the current that the wire is carrying. If the duty cycle of the current is 10% then the wire can carry much more current compared to a current of 100% or continuous. Having said all this, there are tables of ampacities for various sized wires.

Q:I have a SATA hard drive and a SATA cd drive. Is the power supplied through the SATA cable or do i need seporate power cables: there is a sata power cable that u need to plug in, it comes from ur power supply and is a lil different than the normal power cable .

Q:i have a SATA hard disk and i connected it with a sata power cable and recently i bought a sata optical drive and i have no power cable for connecting the drive, so i decided to connect it with the power cable of hard disk(I have two sata hard disk): You might want to get these at a local computer shop though or you'll pay more for shipping than you will for the wire itself. I would suggest the 1 SATA to 3 SATA seeings as we already know you have SATA power connectors.

Q:Hi, Whether it will causes any problem the power and speaker in a same path? I dont have a separate path for speakers to mount it in wall. I plan to use the existing path which is used for other electrical items. If i use the same path for electrical wire and speaker wire, it will damage the speaker or will make any short circuit in the electrical line?Thank you.: It should be fine as long as you do not tie wrap the speaker wire directly to the power wiring. Speaker wiring is pretty immune to interference except for in extreme cases. Just run it as far from the power as you can.

Q:ok, i want to install and upgrade the sound system in my car, volkswagen 2006, but i dont know where to run the power cable from the battery in engine compartment to the trunk where i place the amplifiers, anyone who knows, please help me out. thanks: Spray down the plug wires with WD-40 and enable it set for 10-15 minutes. initiate the motor vehicle and notice what occurs. the reason it runs like crap is that the wires did no longer do a sturdy activity of preserving moisture from getting interior the boot. Now rather of the spark occurring to the plug, this is going to arc to the closest floor direction courtesy of the moisture direction.

Q:I am trying to hook up a LCD display (CPU Temp, USB's in use, Memory Temp/usage, etc) and It came with a 5pin DIN connector for what I assume is the power. I am not sure what I need to do to connect it to the PSU. Any help or ideas?: I think this device should have a power connector as well as a sensor cable (USB in use should have a connector running on to your motherboard.) can you provide me the make/mode number of the equipment. Also provide me with a link so that i could see the connectors and wires and the device. Else take a pic, upload it some image hosting site and provide with a link. (you can edit your question or add additional info and provide a link. Replace the
