- Q: A pair of Copper wire mains, each of 3.87 sq.cm cross section use to transmit the power, a distance of 915m for 10 hours a day, 80 kilo watt at 200 volts are taken from the mains, find power lost in cable per day at resistivity 1.7 micro ohm.cm.Note: Question is talking about A PAIR OF COPPER WIRE
- Power loss per day is meaningless, I assume you mean energy loss per day, or power loss You have to calculate the resistance in the wire. Resistance of a wire in Ω R = ρL/A ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m? A = πr?, r is radius of wire in m resistivity Cu 17.2e-9 Ω-m 3.87 cm? = 3.87 e-6 m? R = (2*915)(17.2e-9) / (3.87 e-6) = 8.13 ohms 80 kW at 200 volts is a current of 80000/200 = 400 amps You cannot put 400 amps through an 8 ohm resistance, as that requires a voltage of 3200 volts, which we don't have. So the premise of 80 kW is not possible. Perhaps you copied one of the numbers incorrectly. .
- Q: I want to put a poe switch into the patch panel and power a few runs throughout the office. Can the end users use the drop as a standard way to plug into a computer or add a switch if they need to split the internet? What if they want to add their own POE switch at the end of the drop?I can't beleive I haven't seen this question asked already! Anywhere on the intternet!thanks for answering
- Yes, you can attach PoE or non PoE devices to the switchports. No worries. If a device is not configured for PoE, than it won't use it.
- Q: Wire and cable manufacturing process (to be detailed)?
- Copper core per square of the safe current (continuous use) for the 2.5A, intermittent use of 4A, according to the power count 550W-880W.
- Q: It's provided to me by my ISP which is Cox. If I were to unplug the power cord what would happen, would my phone no longer work without another technicians appointment. I know that the motorola cable modem with no phone service you can power cycle that one.
- Turn off the modem. Wait 5-10 seconds. Turn the modem back on. If there isn't an on/off switch on the modem: unplug the modem, wait 5-10 seconds, plug the modem back in.
- Q: I need to select a power cord for a computer and other appliances (like a printer). Power cords usually have their amps and voltage (capacities?) imprinted on the outside. What is the rule of thumb for selecting a power cord and why?For example, if my printer has the following requirements:Power Source AC 120V 50/60 HzPower Consumption - 5W-350WWhat amp/voltage type of power cord will do the job?I am of course concerned about overloading the cord with too much electric requirements.(People who actually know this matter SPECIFICALLY only need to reply; please excuse if the electric language is not used right.)
- A 5A cord would do the job.
- Q: What is resistance of the cable (resistivity of copper is1.7x10^-8)Answer is 14 ohms. But please explain how do we get there in full detail.
- Find total cross sectional area of copper in cable ie 12 * area of one. calculate the resistance of 1 m then multiply by 2000.
- Q: My power supply cable to the motherboard is only 20 pin and the motherboard has a slot to take a 24 pin power cord. The 20 pin will fit but 4 slots are just left empty. The motherboard LED light comes on showing it has power. When I try to boot up the motherboard runs but the hard drive doesn't boot or the screen isn't working. Could this be b/c of not having a 24 pin power cable?I know the video card and HD work b/c I just transfered them from another motherboard that was a 20 pin. Any ideas?
- I believe it'll work, 4 pins will just hang off to the side. The same goes for 8 pin power cables to a 4 pin power socket on the motherboard.
- 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 don't know my friend. try calling MS.
- Q: My power supply (tagan 1100w) has an 8pin m/b power cable but the PCIe one looks cooler.
- yes you have ues it
- Q: I CAN'T AFFORD A NEW POWER SUPPLY CABLE/ADAPTER AT THE MOMENT.CAN SOMEONE HELP ME PLEASE.
