Q:difference between power and control cable?
Control cables as their name suggests, send signals to control the functioning of an equipment. Belonging to the family of instrumentation cables, these cables allow distribution of data or signals that have low voltage. Designed specifically for automation controls, these cables have a copper conductor, which is enveloped in galvanized steel braid. Usually used for regions that require less than one ampere, these cables can carry signals up to 40 volts. These cables usually bear a PVC insulation that protects them from impacts and harsh climatic conditions. Power cables are cables, which transfer both high energy and low energy from the source to the equipments. Specifically designed to best suit active and neutral environment, these cables bear a thick outer sheath compared to ordinary Control cables. The external sheath of the Power cables with its immense strength and protection enables the cables to transfer high volume of energy without any tension or strain. Unlike Control cables, Power cables often have a unique colour code system that distinguishes the high voltage carriers from their low voltage counterparts.
Q:do i need a phantom powered cable?
Not okorder.com/... If you have the C-1U version, all you need to do it connect it directly to the USB port on your computer.
Q:Can you plug a power supply 6 pin cable into a 4 pit motherboard slot?
No, okorder.com. I know they have extensions so they should have what you are looking for.
Q:Does Boss blues driver need a battery and power cable?
Have one,Hate it, Blue,s tone my ***,It was a waste of money.Answer Yes,battery has to be installed. will work on battery,or nine volt adapter. Battery has to be in it at all time,s for it to work.
Q:PCI-e 6 pin Graphics card power cable?
That potential supply is right for that card... do not hardship approximately it... The 4890 takes much less potential than a 4870 and my previous equipment with a 4870 relatively purely used 330W with dissimilar 120mm case followers a 92mm and an 80mm... in case you have already got that PSU then save it....
Q:Where do u put the cables?
well for convenience, id run the power cables on the side of the car that the battery is on and the rca's on the other side.
Q:where does the main power cable go on a 50 panasonic viera TV?
It's in the back, near the main power switch but it's up and under. Look from the bottom up and you should see it
Q:How can I use a Power over Ethernet cable to connect to a hub and use PoE and non PoE devices?
familiar ethernet cable is nice for 100m (approximately 328 ft), Any device which includes a hub, router etc. oftentimes acts as a repeater, 'cleansing' and boosting the sign to make greater desirable the variety. The distances you point out will have not any impact on ethernet. besides the shown fact that any undesirable connection or cable alongside the way can doubtlessly injury the sign. I have not any issues extending broadband ethernet hyperlinks over a number of thousands of metres with strategically placed small switches alongside the way for serious enterprise use.

2)Explain why a bird sitting on a 400 kV power transmission cable is not electrocutedmany thanks for your answerPepe
Q:what is the best GPU that doesn't need a power cable?
What do you mean by power cable, it doesnt really matter, its in your case anyway and the 600W is enough to power most decent GPUs for a budget go for a AMD HD 6850/6870, a bit higher go for a GTX 560 TI or AMD HD 7870.
