- Q: Alright, im most likely moving to Germany in December, and im bringing my PS3 over with me. That I bought here in the US.. Is it possible for me to buy the power cable for a PS3 that works in Germany and plug it into my current PS3, or will it short it out?
- It won't short out, cause it will only take certain power
- Q: Copper core power cable laying cable sets what fixed
- SDH is a synchronous time division multiplexing device, the electrical interface of the 2M signal into the optical interface of the high-speed signal (the use of digital fiber optic patch panel SDHsynchronousdigitalhierarchy) 155M, 622M, 2.G, 10G, etc.). 2 trillion of the signal can be in the DDF above jumper, easy to connect. The optical path signal is spanned on the ODF and is interconnected with the optical interface of the cable or other device. Usually with the network, telephone, etc. are specific business, their communication distance is limited, are generally carried through the transmission network to expand the communication capacity, extending the communication distance. SDH is the main equipment of the current transmission network. DDF and ODF are mainly used in the machine room. The physical interface between devices is BTS-DDF-SDH-DDF-BSC-ODF-MSC or BTS-DDF-SDH-ODF-BSC -ODF-MSC Of course, bsc and msc may also have a section of ODF-SDH-ODF, see the specific circumstances
- Q: Big god speed to ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ much needed
- The length of the cable bracket is determined by how much the cable is
- Q: What I really just want to know is the equation and basic concept on how to determine the optimal length of power cable needed to connect two poles while knowing only the linear density of the cable.It does not matter how much sag is produced because of limitations due to the strength of the power cable.
- The web page provides very thorough information and rigorous mathematical treatment relevant to the answer you seek. But it is just too much all at once to digest. So take it piecemeal, one bit at a time! First, you must realize that the sag of the cable is the single most important design parameter and strict attention to cable weight determines the optimal length. The equation of the catenary is the precise model but a parabolic approximation may work. (parabolic approx.) ymax = (3wl?) / ?√(64EA) P = wl?/(8ymax) Where ymax is the maximum sag l is the unstretched length w is the weight/unit length E Youngs modulus A Wire area P axial tension the curve is a parabola, which is a good approximation if the depth of sag is no greater than 1/8th of the span. Use the second equation to derive the induced tension P. H:=WL?/8S S:=WL?/8H L: distance between support S: Sag at mid-span H: tension (horizontal component of tension) The tension depends purely on the loaded geometry and the weight per unit length.
- Q: UPGRADING BIG 3. ARE THOSE TWO CABLES THE SAME THING ? DOES IT MATTER WHICH ONE I USE FOR THE BIG 3 UPGRADE?
- The wire is the same, just different color so you dont confuse yourself when installing. You'll actually have to upgrade BOTH wires to properly do the big 3. 1. + Batt to + Alternator output post 2. - Batt to frame/chassis 3. frame/chassis to engine block 4. (For extra) engine block to - Batt All in at least 0 awg gauge wire. I've done my in 0/2 awg gauge welding cables.
- Q: Can I do the big 3 upgrade by only doing the 2 ground cables(battery to chassis and engine block to chassis) now and doing the power to the alternator at another time? Will this give me a little performance boost until I can get enough material?
- no, that would be a waste of your time. having a fatter ground won't mean anything if the power wire is the same. you would be better doing the power wires only. problem with that is, there will be built up current that can't dissipate fast enough before damage is done
- Q: what cables do i need (besides a power cable) to start playing?
- The PS3 should come with composite cables as standard. The yellow/red/white cables. IF bought brand new take it back and tell them you got no lead with it. How ever if bought second hand, ask the person to send you the composite cables. If they cant the one for the PS2 will do the same job. Also you can use a HDMI cable if you have a HD tv.
- Q: I want to know if the dell vostro 260 has it
- No, lower wattage PSU (typically less than 400 watts) generally do not ace PCI-E power cables as PSU's with that low a wattage typically aren't used in gaming PCs. The Vostro 260 came with a 300 watt PSU and almost certainly does not have a PCI-E power cable. Contrary to what Peter suggests. That computer does have a PCI-E slot. If you have a the mini-tower case you can fit a full sized discrete video card. If you have the SFF case then you're limited to low profile cards, and the PSU is a non-standard sized 250 watt unit. You're probably going to have to upgrade the PSU if you want to get new video card. Also, at best this computer has a Sandy Bridge i5 CPU, with the Pentium and i3 being more common. If you have the Pentium or i3 CPU, then you're only going to want mid-range or cheaper video card, as anything faster than say a GTX 1050 / GTX 960 or Radeon RX 470 or R9 380 will be bottlenecked by the older CPU.
- Q: i hooked up all my 4 gauge power ground cable from the batteries of my truck i passed both of them thru the fire wall but what i was wondering is will i have a problem since its the power ground coming thru the same hole thru the fire wall or will i be all good ? somebodyy help
- Make sure the edges of the hole aren't sharp or rough, to prevent the wire insulation being damaged. Usually, the ground wire on the amp is mounted to nearby metal instead of running a line all the way to the engine. Then, you can beef up the wire from the battery to frame in the engine compartment if necessary.
- Q: Only the ground cable is green, the two other cables are gray and I noticed that one is with stripes the other is not... The maker is Smart Choice. - there is more clue, one cable end is coded with a letter Z , other W , than G .... the G is probably the ground ( green ) . I need to know which one will connect to the black wire and which to the white one. Please help. Thank you
- stripe to white black to plain wire green to chassis. The white is neutral black is line bare wire is green
