- Q:I know they can control networks but what about cable, what is keeping cable channels from just showing hardcore pornography 24/7even showtime has a no bottom/no thrust/no rod rule.I don't have HBO so I don't know what they use, but still do we really need the FCC to censor its obvious that tv channels aren't desperate to put porn on the air so why do we need the FCC (other the the frequency adjustments for radio and what not)
- The FCC controls what is broadcast over the air waves. Cable TV is by subscription only, so if you don't like the programming you don't subscribe. Broadcast TV requires no subscription and is freely available to anyone who turns on a TV set. If the FCC were not there to control broadcast TV you would soon see porn popping up everywhere, since it is about the only thing that sells.
- Q:The difference between power cable and overhead cable
- Insulation structure is not the same, the number of core is not the same. Power cable generally 3-4 phase, overhead cable general core. Power lines can be divided into overhead lines and cable lines. Overhead lines with less investment, easy construction and maintenance, easy maintenance and repair advantages, the disadvantage is the natural conditions (wind, snow, ice, lightning, etc.) have a greater threat to operational safety. In order to save the country's construction funds, the general use of overhead lines is appropriate. However, when the conditions are subject to restrictions (such as overhead lines laid in difficult or special requirements), the use of cable lines. Cable and overhead lines compared to poor heat dissipation, it should be considered in the short-circuit conditions of thermal stability. Therefore, in addition to high-voltage cable cross-section in accordance with the economic current density, allowing voltage loss, long-term allowable current selection, but also according to short-circuit thermal stability conditions for verification.
- Q:if we provide power through power cable will there be need of extra capacitor near load?
- Yes, if you are talking about a bypass capacitor. Electronics always requires a bypass capacitor near the circuit/IC. Having one at the end of a cable means the cable inductance is in series, and the impedance seen by the IC power supply leads is inductive and high instead of the needed low impedance that a local bypass cap provides.
- Q:Basically bought a new graphics card (480 gtx) and im going to install into my computer but i wish to also install a phyx card as well. This seems simple enought but i only have 2 6pin power cables in my pc atm and im am unsure how to install another 2 6pins. Current PSU is a antec 1000w
- You okorder /
- Q:so I bought a new power supply to go with my new case and motherboard, and when I recived the new power supply it didn't have a power cable That Plugs into the wall, can I use the one from my old power supply or will I have to get a new one? Cause I tried using it and my pc didn't turn on, or is my power supply that I got possibly dead?
- every power supply I've gotten for years uses completely standard, detachable power cords. I've never yet seen one that will not use the same cords as all the others. Use the one from the old supply
- Q:should you run RCA cables and power next to each other?
- Keep em seperate or you'll risk engine whinning or other noises. Run the power wire on the left side and signal cables(RCA's) on the right side of the car.
- Q:At the end of every work day I shut it down in the normal way (through the Start Menu) and then every morning I return to it and it won't turn on no matter how many times I press the on button or if I hold it down.The only way I can get the computer to turn back on is to remove the power cable for 10 minutes and then put it back in and hold the on button for about 10 seconds. This is a bit of a pain but also quite worrying as the computer is new.I wonder if my computer is broken or if this is an intentional feature. If so how do I turn it off?It might help to know that even when I have shut it down there is an LED on the back that stays on. In fact it stays on for 5 minutes even if I take the power cable out!I have a Dell Vostro 260S PC. It runs Windows 7 64-bit and the processor is an Intel i3Please help techies.
- in the journey that your useful this isn't application appropriate !! First replace video card with on old pci card you recognize works .(you should disable onboard video if contemporary, agp, and pci-e and set to pci in bios) If it runs with out freezing then its an over heating video card. ( very regularly the case) on your bios ; regularly , there's a temperature application that has a temp decrease for cpu and mom board. locate out what your cpu and mom board operating limits are from their producer, not DELL.( DELL gadgets them lowwer) that's going to close you down and not in any respect assist you to boot until eventually it cools down in case you go with to confirm if its the mummy or cpu a million) take off the aspect panel the position you face the bottom of the mummy board and positioned a house fan in the front of it. If it doesnt freeze then the mummy board is over heating ( If it does 2) take off different aspect panel and position fan dealing with the ram ,video card, and cpu. Does it close down( if it does) One decision may be to purchase a a lot more advantageous fan ,warmth sink and thermal grease, this may help, yet when your cpu has over heated to many cases not something can help you. the mummy board will stick with the way of the cpu; almost immediately, if not collectively not in any respect positioned a pc in a table enclosure of any form ! And sparkling the interior( mutually with all warmth sinks , followers , and potential provide) periodically !! preserving your pc by technique of a chilly air go back as against a wall with a warmth sign up can help you
- 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:im looking at installing an amp and was wondering if its fine to go through the firewall were there is already a group of wires with a rubber seal, i was thinking of poking a hole through the rubber seal and running the power cable through there would this be a suitable option. Thanks
- Of course you can. As many amps that I have installed I have only had to drill one hole through the fire wall. As long as there is a grommet you are good to go. You should be able to open the rubber up with a screw driver. Just be careful not to damage any wires.
- Q:If Not What Do I Have To Look Out For Because Im Looking For A New Power Supply Fan.
- To be honest, by the time you dismantle your power supply and find the right kind of fan (no, not usually the same, generally smaller) and then glue it all back together, it would be a lot simpler just to get a new PSU.. They're really very cheap, and a lot less hassle to subsititute than to repair
