- 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: What is the power cable accessories used to do?
- Semi-conductive shield The semi-conductive shield is usually disposed on the outer surface of the conductive core and the outer surface of the insulating layer, referred to as the inner semiconducting shield and the outer semiconducting shield, respectively The semiconducting shield is made of a semi-conductive material with a low resistivity and a low thickness Internal semiconducting shielding layer is to uniform the outer surface of the electric field, to avoid the conductor surface is not smooth and the core stranded by the air gap caused by the conductor and insulation occurred partial discharge The outer semiconducting shield is in good contact with the outer surface of the insulating layer and is electrically connected with the metal sheath to avoid partial discharge of the metal sheath due to defects such as cable insulation surface cracks For non-metallic jacket in the low-voltage power cable, in addition to the semi-conductive shielding layer, but also to increase the metal shield Metal shield is usually made of copper or copper wire wrapped around the main play the role of shielding the electric field
- Q: got 1 amp in the back,i want to add another amp at the front without a distrubuter,could i trail another power cable from the battery to the amp?
- Yes but there is no might it will kill ur battery really fast.
- Q: ill exlplain more the battery is connected to one end of the fuse then i want to run 2 power cables out of the other end to both of the amps will tis work or will i just loose power the fuse is 60A if that helps. 60A is massive why a fuse that big is needed i dont no
- its ok you can do it, because the fuse is 60 amp
- Q: When the tv repair company comes out do they take your tv power cable or have there own one for tv
- All TV repair people have all the power cables they could need. BUT... if they think that your fault could simply be a fault in your cable, then they may take it with them, though they would be more likely to try swapping it on your premises before removing the set.
- Q: The hdd i am looking at is OEM nearly everywhere so i'm wondering what i would need to use it.
- just the data and power cable and if your mobo doesnt support that type of drive (like if it only has ide and you want sata) then you will need a controller card
- Q: can you use a standard molex power cable on a SATA HD or do you have to use a SATA power cable to power it?
- depends on the drive.. sometimes a drive will have a 4 pin molex and a SATA power plug.. most newer drives will be SATA only though
- Q: I just recently bought an amp from my friend. It is a fender frontman 15 w amp. I think it is one of the ones that comes in the strat pack or something. anyway, she didnt have the power cable for the amp that plugs into the back, and i kind of need this. does anyone know where i can find one or buy it. I already looked at fenders websight. anything would helpthanks

- Q: When doing competition, is there a rule where your battery in the back can't be bigger than the one in the front? Are Monster Cables as good as they perceive to be???? I.E. their 400 series cables that are wound in different arrays to optimize each frequency out put? Can a Power cable actually provide more efficiency if constructed right, once again, their 400 series?Subwoofers being 1000 RMS but only getting 500, will running them at their RMS make a significant difference?
- Power cables are very very important when running a comp set up. You want as much current running through as you can possible get. Same goes for your ground, you want it to be just as good. Monster Cables are a very good brand of cable. RMS is basically the wattage a speaker can take continuously. If you run twice as many watts through your amp it will be significantly louder and boost your SPL.
- Q: How do power-station-cable thieves manage to get away without being electrocuted?
- Police are hunting for a badly scorched would-be copper thief after finding a hacksaw embedded in an 11,000 volt power cable. The thief also left a lit blow torch at the scene. He is presumed to be badly charred, and not the brightest bulb in the socket. .
