Q:Power, Resistance of cables?
I think you went wrong with the length. If R= (resistivity x length)/Area, make sure you are using length as 500,000m as the units should be in meters, not km. R is going to be 75 ohms because you are considering the entire length. Then solve for area and radius.
Q:Computer host configuration of about 1,000 yuan (preferably 1000 below) - probably as follows;
Cable trench as a power construction project should be cable trench construction construction design, cable trench construction program, according to the previous design requirements and programs in order to develop cable trench construction quality acceptance procedures
Q:video card upgrade, power cable too short?
just buy the long cable...easy right?
Q:Does the eVGA GT 440 graphics/video card need a power cable connect from the psu to it?o?
No, it doesn't need one, but it's also a crappy purchase. The Radeon 6670 costs about the same, doesn't require external power, and slaps the GT 440 silly.
Q:What is the difference between KVV and VV cables and are they clearly different?
Eight or six no less, the first good fire retardant pipe on the line, the box can be opened after the slot
Q:Whether high voltage cables can be built in belt corridors
Power cable accessories are divided into several types, commonly used is heat shrink cable accessories, cold shrink cable accessories. (1KV, 10KV, 20KV, 35KV), several models (indoor, outdoor, intermediate connection), each containing the components are not the same, but there are all kinds of cold Heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable tube, sealant and other operating accessories.
Q:what happens when A power cable of copper is stretched straight between two fixed towers.?
Change in length=(coefficient of expansion)(original length)(change T)= (.0017)(chose your favoret length, I chose 100)( -128 because T is decreeing)=-21.76 Strain = (change in length)/(original length)= 21.76/100= .2176Pa (for simplicity's sake I dropped the negative, rember the wire is in tension) Stress = (youngs modulus)(strain)= (11•10^10)(.2176)= 2.3936•10^10 Pa The UTS (2.4•10^8)<(2.39•10^10) so there is definitely necking and because of the difference most likely there was failure long ago.
Q:Power cable question.?
Possibly on the BoxiT-200 that takes 12 to 19 volts at 3 amps, positive center. Read the printing on user manual, it gives the requirements. Most other Elmo projectors are plugged into an ac outlet.
Q:Universal laptop power cord...can somebody recommend a good but inexpensive universal power cable for a laptop?
Laptops each have different power cords, because they have different connections to the laptop itself, so there's no one universal power cable. However, you can easily buy generic powercords for your specific laptop that are cheap. Just go to a site like OKorder and search for your laptop name.
Q:Why does my graphics card have an external power cable included?
Some graphics cards require you to connect a power cable to the board. As it requires more power than it can get through the pci connection.
