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:LCD monitor help. Where is the power cable?
That means it requires an AC Adapter. You need to know the power requirements for the monitor, then you can go to Radioshack get an A/C to DC adapter that provides the power recommended
Q:We say that the size of power cable is 4 core, 150 sq.mm. What would be the diameter of this cable ???
A 4core (electrical) cable of that strength is usually built up from quarter circle shaped sectional wires. (Think of a pizza cut into four even pieces.) So, calculate the outside diameter from this point and add 4 times the insulator thickness. Example: 400V 4core cable has very likely 1mm insulator thickness. 150mm² * 4 cores is 600mm² total. By A=PI*d'*d'/4, d' being the diameter without insulator, would be d'=2*sqrt(A/PI)=600mm²/3.1415...=2*sqrt(...‡ Now, as said above, add the 4 insulator layers, and then you would be at approx. 31.7mm outside diameter.
Q:please any one tell me the formula to find the current capacity of power cables?
Hi Sherlock, You need a copy of BS 7671 The IEE Regulations. By the cable sizes mentioned you must be in the UK. The current carrying capacity of a conductor is a function of its Cross Sectional Area, Length, Method of installation, Is it grouped with other circuits, Ambient Temperature and fuse or CB type. (these are called multipliers) For larger cables the power factor of the load must also be considered. The basic formula assuming no multipliers are used is Volt Drop per ampere per metre X length of run X Design current / 1000 Volt drop is from the tables in BS 7671 Length of run is the cable length design current is the current the cable will have to carry in normal use 1000 is because Vont Drop per Amper per Metre is given in millivolts
Q:I have a Compaq Laptop R3000 and I need an alternative power cable?
I think this is the cable you are looking for. Found it on OKorder. Connect your notebook PC directly to your TV or stereo system with this handy 8' HP xc1000 Notebook All-in-One Media Cable that does it all (S-Video composite TV, digital audio, and analog audio).

Q:imac G4 power cable Question?
specific. the means cords designed for the iMac are what's mandatory to function the iMac. the present twine probably isn't feeding adequate means to function all stages of the device. that could happen. substitute the twine. optimistically, which will remedy your subject. stable success.
Q:can i use SATA power cable of SATA hard disk for connecting SATA optical drive
while you're meaning are you able to boot off of the IDE annoying force and get entry to the Sata force, the respond is sure. in basic terms connect the SATA annoying force, and make beneficial the BIOS settings are set to boot from the IDE force.
Q:Can i switch power supply cables ?
hardship examining your question. Are you asserting which you have microprocessor that hangs once you're utilising a generator? is the generator powering the microprocessor? sure, interestingly that noise spikes or another noise from the generator is inflicting the reminiscence interior the processor to be changed. Is the processor in a shielded field? the ability grant? Are there any filters on the generator? all of those can help. Are there any archives lines linked to the processor? they could be the best suspects. they might could be shielded.
Q:Cable yjv-0.6 / 1kv-4 * 120 + 1 * 70 What does it mean?
To use the video card at the same time connected to the computer monitor and TV show together, have to do the following: 1) graphics card must include HDMI, including two or more signal output interface. (Such as the shadow GTX650 there are DVI, VGA, HDMI three signal output interface.) As long as the graphics card to meet this requirement, no matter which brand can be. 2) graphics card HDMI interface has to support the original sound decoding, that is to say with the HDMI cable and TV connection will have a sound output. 3) in the TV or computer monitor line to use straight, can not transfer. Because a card when the transfer may not show. 4) After installing, enter the display adapter from the Start menu. The contrast display to set, to show the same content to select the copy; to display different content on the choice of expansion on it.
