- Q: What is the difference between VV22 and VV62?
- The conductor of the cable is resistive, and the current when the cable is running through the conductor to heat up. In a certain installation, ambient temperature conditions, the heat generated by the conductor current and cable in the operating environment under the conditions of the heat dissipation is equal, when the current is safe operating current, which is commonly referred to as the cable carrying capacity. Cable carrying capacity is in a certain installation, ambient temperature conditions, the load, so the installation, the ambient temperature conditions are different, carrying capacity is different from the ambient temperature changes, the safe current is also to change. Therefore, if the cable is running at a certain installation and ambient temperature, if the actual carrying capacity of the cable exceeds the safe cut-off, the heat generated by the conductor is greater than the heat of the distribution, the cable will heat up; the same time when the ambient temperature increases The ability to heat down, if the current carrying capacity is not reduced, the cable is to heat.
- Q: I lost my PS3 power cable but I got one from an old pc and it does work but am i better off using my old cable?Does it affect my PS3's performance?
- some PS3s have usual means furnish. to comprehend which one you have you are able to desire to open it. in case you do no longer prefer to open it (and void the guaranty) - use means converter. notice: for PS3 you will prefer a minimum of four hundred Watt. As for means cable itself - relies upon on the socket on your means converter.
- Q: Recently I bought a EVGA Geforce 8800 GTS. When it came in, the card fits in my case but has 2 cables to plug in. I only have 1 cable to plug them in connected to my power supply. Should i only plug in 1, or is it nessesary? Is there an extra one I just dont know about? Please answer!
- You need to get a power cable splitter that goes from two to one. It should have come with the card, if not any local computer store should have one.
- Q: There are a few thin cables running from the power button on your computer onto the motherboard. What are these cables called?
- It's not important to call them with a specific name. These are also cable. If your power button's cable is broken or damaged anyhow, you can change it by restart button. Just unplug the restart button's cable plug them in Power switch. Now your restart button is your power Switch
- 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: the power cable is in 2 parts, one from the xbox to a box, from the box to the wallthat box has an led light. when the xbox is on, it should turn green, when the xbox is off it should turn orange. my led light is turning red instead of orange and green.its not red ring of death, or 4 red rings, i know this because my xbox wont even power up because the box in the power cable will not send power to my xbox. im so confused...plz help
- I can't answer your question coz I've got the same problem too! can somebody please answer his question?
- Q: My system was working fine until today. The bass stopped hitting to the music and thumps in intervals of about 5 seconds regardless of whether the music is turned up or down. I hooked up my system without my capacitor to see if this was the problem. It worked...but only for a minute. The bass was hitting like it was suppose to but all of a sudden it went back to the interval thumping and the power cable got hot to the touch and the fuse inside the holder was melted. What the heck is the problem?
- short circuit. you need a bigger fuse in the inline cable coming from the battery. bigger fuse
- Q: NE1 have a surge protector and power filter for there home theatre stuff? If so what is the model and did it make a difference? I have RF grounding problem through my cable and was wondering if the moster cable boxes would help clean up the signal. I have to wrap a wire around the coax cable and ground it to something to make SOME not all of the noise dissappear. (lines rising from bottom to top of picture) Obviously I want a more definate and permant solution. Thanks.
- Yes, a power conditioner will not only clean the power, but take out any humming or ground loop issues. I noticed a difference in audio and video. I have a Monster Power MKIII 3600. I got it for $200, on sale at Circuit City a year ago. I highly recommend it if you have a multi-component home theater or expensive TV. I have a 50 plasma, DVD player, Comcast box, AV receiver, Xbox and Nintendo Wii. They are all connected through the power conditioner.
- Q: One of my ottocinclus is munching on a little brown algae that's on the aquarium heater's power cable. Not dangerous, I guess? I don't think they can actually bite through it and expose the wire...?
- No it isn't dangerous at all. He will be fine. I love otos. They are so darn cute.
- 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
- The principle is simple. VI=constant. Energy loss is proportional to I^2. If you want transmit power over a long distance, then V should increase. So the current will be small and energy loss will less. You can not use it because, high voltage gives more shock. When bring it near the home, reduce the voltage so the items becomes less shock giving. Welder use very high current and very low voltage may be 6o volts so that they do not get unnecessary shock.
