- Q:or do I need to buy one?
- No, the PS3 is a 3 prong outlet cable, and the PS2 is 2 prong. Also the end that plugs into the console is different for both. You can use a PC power cord for the PS3 if needed, the ends are the same.
- Q:I have noticed on some power cables there is a quot;bumpthat the cable is wrapped around what looks like a magnet. Why?
- it's called a ferrite choke and are used in a wide range of prevention of electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines and for prevention of malfunctioning of electronic equipment.
- Q:I live in the UK and I am going on holiday to Taiwan/Japan where the voltage is 110/100v as opposed to 220 here (i think).I was wondering if I could use a power extension cable (with multiple sockets) so that i would only need one adaptor to connect the extension to the mains and then I could just simply plug my 3 pin plugs into the cable saving me money and sockets. As it would be a lower voltage, I assume that there shouldn't be any problems with power however, if there are any electricians or anyone who has done this before I would really appreciate some guidance just to ensure that this is safe.Thanks is advance.
- You'd use the correct AC power cord that replaces the toggle-head part, and that would be the best part. These can be bought with a variety of different ends on them; while the adapter itself will work with any of the supported voltage ranges, automatically.
- Q:What are the advantages and disadvantages of separating 28Vdc, 200A positive power cables and returns into two different harnesses?
- WHAT ARE YOU TALKING ABOUT ? ALL DC POWER SOURCE REQUIRES TWO SEPARATED CABLES .
- Q:Two things:1.) Why when we're using an AC to step up the voltage the power has to remain constant?2.) Why is it if we increase the voltage by a factor of 100 we have to decrease the current by a factor of a hundred and therefore I^2R is decreased by a factor of 10,000
- Power is generated at the power station and transferred to the end user your home by means of power cables. Unfortunately, some power is always lost in this transfer process. It's power NOT Voltage OR Current that is required to operate your home electrical appliance. Yes, current and voltages are involved ;but it is the PRODUCT of these two that makes up the power NOT the voltage or current individually. Power = Voltage x Current Power is lost in the cables as heat as given by your i^2R. To reduce the losses then we must reduce the current I. But, if I reduce the current and keep the voltage the same then the power will fall and my kettle/Xbox/curling tongs will no longer work at home. So, to keep the power up when reducing the current I must compensate by increasing the voltage and this means using a step up transformer. Near the homes, a step down transformer is used to reduce it back down again. Since the losses in a cable are a consequence of I^2R heating then it is important to reduce the current as much as possible when transferring power. If we assume the the resistance, R of the cable is constant, then a 10,000 reduction in power (power/10,000) gives P/10,000 = I^2 x R I^2 = Power/10, 000R I = square root of [const x 10,000] I = 100. Then using power = voltage x current reducing the current by 100 means increasing the voltage by 100 to keep the power the same.
- Q:So, recently i purchased a new graphic card and it requires two 6 Pin PCI Express Power Cables. My current power supply generates 650W and only has 1 six pin PCI express power cable. Im at a loss to what to do now. Do i purchase a new power supply that has more pci express cables? Or do i open it up and add a new cable? Thanks if you can take the time to answer my question.
- You're going to want to buy a new power supply that can handle it. To require two cables, this card sounds like a behemoth and you're likely going to want a bigger supply anyway. Adding a 6-pin cable isn't really a thing. I'd recommend Corsair for any supply as they're high quality and cheap.
- Q:There is no load in the middle of the problem added: the laying of the laying, and now the longest cable can do more long
- Network set-top box does not require a computer, only need to follow the operating manual set-top box and TV connection, and then boot the wired / wireless network configuration, with set-top box software can watch the video program. 4M do not see the basic high enough, but now the Chinese network is shared bandwidth, if the use of many people may be cardton
- Q:Why do phone lines stay on when other lines power and cable will go out during a storm?
- I'm just amazed at how little people know about everyday things. The phone company actually runs their phones on BATTERIES... so when the power goes out, the batteries keep the phones alive... it has been done this way for OVER 100 YEARS... so it's nothing new.
- Q:Suppose load is 100KW, length 50m, how to calculate cable size. If we know current Is any easy mathod to calculate cable size.
- There are two issues to consider, cable heating and voltage drop. Of the two, voltage drop is by far the easiest. You need to determine what the allowable voltage drop in you cable is. The voltage drop is just I x R where I is the current and R is teh round trip cable resistance. The specification of 100 kW isn't enough. If its a high tension 100 kV line, the current is only 1 amp and a run of 16 AWG wire would deliver about 99,999 volts out of the original 100,000 volts to your load. If its a 100 volt system then a 4 AWG wire would only deliver only 20 volts to the load. The formula for wire resistance (in AWG) is that 10 AWG has 0.001 ohm/ft. Each increase of 1 in the gauge increases resistance by the cube root of 2 (about 25%). You calculate by picking what voltage drop you can live with, for the known current figure the resistance, knowing the length figure the resistance per foot, and then pick the AWG using the above. The second concern is wire heating. Although you could do the heat transfer calculations, instead look up the allowable ampacity for any wire in an electrical engineers or NEC handbook.
- Q:I have recently decided to scrap my capacitor and need and extra two feet of power cable in order for it to reach the amp....is it possible to splice and join two power cables together or is it a better idea to rewire with a longer cord?
- The only way to properly splice the cable is to solder the cable to another piece of cable the same size. The best insulator is brush on tape , just make sure whatever you choose to use, it is sufficiently wrapped. There should minimal power loss if care is taken to make the connection well. However, the best way would be to run a new cable. But considering the trouble this may pose, a quality spice may be the best choice.
