- Q: Currently I have a 250GB drive and Writable CD/DVD. I wand to add a 3.51TB internal drive
- you have such a small case, i doublt that there will be room inside the case for another internal drive. if there is room, the PSU should have an extra Sata power connector and you will need to get a Sata cable if you buy an OEM drive, if it's a 'retail' version of the drive then you should get a Molex to Sata power cable and a Sata data cable. you probably wont have space inside the case for another drive, go with a USB 2.0 external desktop drive.
- Q: Explain why a bird sitting on a 400 kV power transmission cable is not electrocuted?
- Simple . It is not grounded.A curcuit has to be complete for electricity to flow through it.
- Q: can we use welding cable to hook up amp in our car?rated 200amp
- There is no need for a 200 amp cable. most of the time 75 to 100 amps is more than enough. Just go to the local car audio store and pick up a amp kit. (Depending on amp size depends on price) The local Wal-Mart sales them as well. You'll spend between $25-$100 for a good amp kit. Amp Kit 1 power wire 1 ground wire 1 set of RCA for audio from sterio to amp 1 fuse.
- Q: I recently switched to cable tv ,internet telephone. i now have 2 tv converter boxes + modem box(?) on 24/7. i did not have that equipment before.my electric use is up 1.5 kw a day vs last year since the change. at first i blamed it on a warmer summer. but the last few weeks have been mild and the new bill today is still higher.did changing and the new equipment cause the extra electric use ?
- look at the back of each device. it will show you a current rating and usage, exmple 45 watts. Add em up Whats strange is that they draw power even when turned off.some even more when off. use a power strip with an on off switch so you can turn them all off when not in use. Turn them all on watch your electric meter spin. Unplug them and watch it spin. The difference is your savings.
- Q: Wire and cable manufacturing process (to be detailed)?
- Tell you an electrician commonly used "empirical formula": as long as the copper wire, cross-sectional area per square millimeter can be safely through the 4 - 5A rated current; in 220V single-phase circuit, the power per 1KW, the current For the 4.5A or so, in the 380V three-phase balanced circuit, the power per 1KW, the current is about 2A, the above values can be calculated using the physical formula is very close to the results, so the electrician at work, in order to Do not remember those "cumbersome" formula, remember that these can. Then according to this algorithm to know: every 1 mm square cross-sectional area of the copper wire, if used in 220V single-phase circuit, you can safely carry 1KW load through the current, if used in three-phase balanced load (such as motor) Circuit, you can safely carry 2.5KW load through the current
- Q: the contant power cables go to my car alarm, led lights, siren, power locks, power windows, and alarm bypass... they are very small thin awg wires... the ignition and constant power cables under ignition housing are alot thicker... is this possible with no problems?
- I wouldn't tap into any wires where your alarm is.. If you have any issue, it could arm your alarm, and you might not be able to start your car, until the wiring was fixed...
- Q: i replaced my ps2 power ribbon cable with a slightly diffrent ribbon cable but it had all the connections just like the original one. i plugged in my ps and i heard that slight clicking sound of the electricity entering the ps2's cuircut such as it always has when it was working fine. but when i plug the ps2 in the lights on the power buttons wont come on and they havent come on no matter whitch way i turn the cable. i would really like to get back to KH2 bugt this is getting annoying. what is up with my ps2 that even though everything is connected i cant seem to get the power lights to come on. help!
- BECAUSE YOU TOUCH YOURSELF AT NIGHT
- Q: How do I get it not to do that? Its really annoying. Whenever I remove the charger cable , the screen gets really dark. It seems like an actual function and not a defect, but is their a way to toggle it on and off?
- Thats how its made. Laptops dim screens to save battery power. To override the setting, look for a picture of the Sun on the middle-top of your keyboard. Sometimes its Blue. Once you find it, look at the bottom left of your keyboard for a FN (function) button. While holding the FN button, tap a few times at the sun button. Your screen should now be bright ;) Make sure you do this with the power unplugged, enjoy.
- Q: How to choose the type of street lamp cable specifications, anxious
- laying the dark tube should be used when the steel pipe or flame retardant PVC pipe
- Q: Is a graphics card power cable needed because not all graphics cards come with one? And if it isn't needed, what is the benefit?
- not all graphic cards need them. But lately the graphic cards are using up quite a bit of power, especially the high-end ones. So if the graphic card has a pci-e power connector. Chances are it will need it. Otherwise your computer might show graphics are there will be error when trying to play games or other graphic intense applications. The same thing is happening to graphic cards, that happen to processor a few years ago. Not that long ago processors could just be powered by the energy coming from the bus line on the motherboard, but that is not true anymore and now we use 4-pin or the new 8 pin axillary power for the processor.
