Q:I bought a LG Plasma TV, it comes with 3 Ferrite cores, two of them is a little bigger than the diameter of the power plug and it's not tight on it and one is small, is it effective to but the bigger one one the power cable?

It doesn't make any difference, they are just as effective if they are loose. Actually the bigger ones should be more effective at filtering because there is more ferrite material in them.

Q:I have a Netgear router and just now when I tried to plug the power cable back into the back of it, it would fit. I look more closely and it seems that the metal end of the power cable may be slightly bent. But I'm still confused because it's bent at the end of the metal, and even though the very tip of it isn't bent, that part still won't even slide into place a little. Could anyone help me in resolving this issue?

If it is the correct adapter for the router and it fitted before, gently force it and it will comfortably fit eventually. There is probably a reason it doesn't fit now (it has been pulled out with some force) so I would suggest getting a new power adapter for it if the above does not work

Q:Hi, I have a router connected to the internet, but one of the computer is 80 feets away from the router and it can not get 100MBps. I have force the computer to use 10MBps. Could someone please let me know what will impact the speed of cat5 cabling?

Power cables cause interference as well as distance and twists in the wire. I assume you have a cable that you made. Did you try a pre-made cable at a shorter distance to see if the ethernet card will do 100mb at all? If it works with the premade, you might have not wired the 80' cable correctly. Make sure you have the pairs crimped correctly in the connector. Pins 1 and 2 are a pair. Pins 3 and 6 are a pair. Pins 4 and 5 and 7 and 8 are paired as well. Example: Orange/white = pin 1 Orange=pin 2 Green/white=pin 3 Green = pin 6 Blue = pin 4 Blue/White = pin 5 Brown/white = pin 7 Brown = pin 8 I hope this helps.

Q:I bought a used DVD player that didn't come with a power cord or power cable.On the back of the DVD player, the power cable input looks like this:__________|_o__|__o__)So basically it looks like the power cable should have two wires with one side being flat and the other end being a half circle.What is the technical name for this power cord so I can easily find it if I go to Radio Shack?Thanks.

Ask for a 6 ft AC power cord. They come in a few difference shapes so just describe what you did here. If it helps reference Radio Shack model/catalog number #61-2878. Good luck!

Q:I need a power cable for an XBox 360. where can i buy one?

Circuit City

Q:What type of cable is the power cable?

Our unit to do the professional cable tray to the current domestic ranking before 3 I did not see we have this certification ah there is a professional health and safety management system has an environmental management system and other quality management system of other scientific and technological innovation patents have a lot of what I do not see the CCC, but you can do the next try you can log in China certification recognized information network - expert column, consult the above experts, these experts have all walks of life experience, can help to you.

Q:On my power cable, (the thing that plugs into the wall, and laptop to charge it) well in the middle of the cord, there is a rectangle black box. What is it called, and what is the purpose of it?

its a transformer to cut the mains plug voltage down to the same voltage as the battery which will be around 16volts to 20 volts for a laptop,the desktop PC will have the same transformer built into the tower casing beside the fan,but you just cannot see it, and there will be a voltage selector switch for the country you are using it in ie-UK =220-240volts, USA=110 volts or similar,both the laptops and desktops use the same internal operating low voltages,and mains voltage would fry everything inside ,that's why they are fitted with the transformers.

Q:I need the cable for my TV to be longer. It uses a 10A 125W cable, and all I can find (at a price I like) are 13/15A cords. Is it okay to use this in conjunction with the 10A TV power cable? It will be plugged into a surge protector if that makes a difference...

The 10 amp and 13 amp ratings are just the maximum amount of current those cables are made for. Your TV will only use 2 or 3 amps, so both cables are fine.

Q:If Not What Do I Have To Look Out For Because Im Looking For A New Power Supply Fan.

Power supply fan is fan inside the power supply, which is the box inside the case of your pc that the main power cable to the pc plugs in to. Case fan is the fan inside the case that provides ventillation to the case. In some power supplies, the power supply fan will act as a case fan by sucking air from inside the case and redirecting it through the power supply then outside the case. This type of power supply is unusual though. in most situations the power supply fan does not act as a cooling system for the case. (and therefore does not act as a case fan). If you replace your power supply fan be VERY CAREFUL as they are extremely dangerous to work on because they deal with direct current from your power socket. The fans inside the PSU are attached by 4 screws to the metal enclosure. usually they are attached to the circuit board by a plug. I have teken a few to pieces and hevent seen one which requires soldering. That may be the case with some models though. USE EXTREME CARE if replacing a power supply fan!!!! Replacement power supplies are very cheap and can be picked up for about $25. If its the PSU fan, it may be simpler to just replace the unit (a new fan is by itself about $10) So for about $15 you can have a whole new unit with no risks to your machine or to your health :o)

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. .
