Q:Do I have to use a fuse for the power cable on an amplifier, if the amp is only a 350 watt amp?

look at the fuses on the back of the amp, total those up and there's the fuse size you will need to use on your power wire.

Q:I bought a power wire off a dealer and in order to connect it to the battery I don't have the little fuse box at the end like most people have. Is this necessary for installation? Cause my friend said it might cause a fire..im no expert?

The fuse isnt mandatory but its a good thing to have if your drawing alot of power then you will need it ive blown like 4 then i upgraded no more blown fuses but ya you should get one

Q:I am trying to modify my my xbox 360(put it into a pc tower that I have) but the DVD power and sata cables won't even come close to reaching. As well as the cables needed to move the rest of my peripherals. Please point me in the right direction or to a website that has these cables for sale. I need 10 inchers if possible. Thanks in advance!!!

Open QuestionShow me another ? What is a good entension cable for the xbox 360 sata and power cables?

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

Power is generated at the power station and transferred to the end user your home by means of power cables. Unfortunately, some power is always lost in this transfer process. It's power NOT Voltage OR Current that is required to operate your home electrical appliance. Yes, current and voltages are involved ;but it is the PRODUCT of these two that makes up the power NOT the voltage or current individually. Power = Voltage x Current Power is lost in the cables as heat as given by your i^2R. To reduce the losses then we must reduce the current I. But, if I reduce the current and keep the voltage the same then the power will fall and my kettle/Xbox/curling tongs will no longer work at home. So, to keep the power up when reducing the current I must compensate by increasing the voltage and this means using a step up transformer. Near the homes, a step down transformer is used to reduce it back down again. Since the losses in a cable are a consequence of I^2R heating then it is important to reduce the current as much as possible when transferring power. If we assume the the resistance, R of the cable is constant, then a 10,000 reduction in power (power/10,000) gives P/10,000 = I^2 x R I^2 = Power/10, 000R I = square root of [const x 10,000] I = 100. Then using power = voltage x current reducing the current by 100 means increasing the voltage by 100 to keep the power the same.

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: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:Ok, i know it is definitely a NO-NO to run my power cable through walls, but, what if I run the power cord through only to pull it out behind my entertainment center from the wall-plate my other cables come out, and plug in a surge protector?

Try running a plastic conduit on the face of the wall and paint it the color of the wall instead.

Q:Power cable ZRYJV-4x70 + 1x35 What does it mean? Can you explain it?

2 cable in a variety of environments in the laying of the layout, spacing should meet the design requirements

Q:(for example : 1sqmm, 4sqmm, 35 sqmm) i need a formula to calculate current by knowing the area of the cable?

Hi Sherlock, You need a copy of BS 7671 The IEE Regulations. By the cable sizes mentioned you must be in the UK. The current carrying capacity of a conductor is a function of its Cross Sectional Area, Length, Method of installation, Is it grouped with other circuits, Ambient Temperature and fuse or CB type. (these are called multipliers) For larger cables the power factor of the load must also be considered. The basic formula assuming no multipliers are used is Volt Drop per ampere per metre X length of run X Design current / 1000 Volt drop is from the tables in BS 7671 Length of run is the cable length design current is the current the cable will have to carry in normal use 1000 is because Vont Drop per Amper per Metre is given in millivolts

Q:Hey guys I have a compaq sr5550f desktop the power light under the cable is flicking green but the computer will not turn on or off yesterday it was fine but unable to connect to the monitor I have saying no signal? whats up with it it was fine two days ago I unplugged all cables and let it rest and still the same result even if i unplug all the cables it still flickers green the dies off then if i plug it back it does it again help?

Does the fan spin (at the back, near where you plug in the power cable) at all? If not, you probably have a failed power supply that needs replacing.
