Q:lost the original cable at a gig, but I have another cable. the outlet on the Behringer guitar amp reads quot;Use only with 250V fuse, but right above the outlet it reads 220-240 with a upside down triangle next to it (not sure if this represents volts or not...I know obviously V stands for volts, but this is a upside down solid triangle.)My power cable/cord that i found reads 10A 250VI know i should probably purchase one direct from the manufacture, but that is not possible right now. I have a gig coming up this weekend.thanks for any help.I also mention the original power cord was a two prong (that went into the outlet) - the one i might use is a 3 prong. will this still be safe? It does fit into the back of the amp perfectly.

Assuming you're in a place where the outlets provide 220 to 240 volts, it's fine. The 250 volts on the power cord just means it's good for *up to* that.

Q:Where can I find a power cable for an HP Photosmart C3180 printer?

why don't you e-mail HP see if they will send you a power cord or advise you where to get one in your area

Q:i hooked up all my 4 gauge power ground cable from the batteries of my truck i passed both of them thru the fire wall but what i was wondering is will i have a problem since its the power ground coming thru the same hole thru the fire wall or will i be all good ? somebodyy help

listen to what AERO D said... you should use self tapping screws,, estimate 50 cents each and drill those into the frame of ur trunk... the frame will have paint on it so be sure to take some sand paper and just clear the paint for best conectivity..

Q:Can I use a standard 12 volt power cable on an Elmo projector?

Possibly on the BoxiT-200 that takes 12 to 19 volts at 3 amps, positive center. Read the printing on user manual, it gives the requirements. Most other Elmo projectors are plugged into an ac outlet.

Q:i have the computer powersupply 400w and i dont know what cable to connect to the car stereo???

if you have a volt meter eather of the black wires are ground you will see a red and a yellow one is 5 volts and the other is 12 volts the 12 volts wire paired with one of the black wires will power your car audio

Q:having trouble finding a spot to run a power cable throught the fired wall of a 97 oldsmobile cutlass supreme

Your fuse panel might desire to be interior the automobile, and you will pull a cord off the fuse block (fuse section, no longer battery section). If no longer, you could pull a warm cord off the cigarette lighter. some autos, like my spouse's Honda, have the lighter on switched voltage (turn the biggest off and the lighter is going ineffective).

Q:Also why is it called quot;phantompower? Don't you think there should be a seperate category for technical questions about music!!?

Yes, you can use regular XLR cables for microphones that require phantom power. The only reason why some microphones require phantom power is because they require extra voltage flowing through the XLR cable. Condenser mics are the most commonly used mics that require phantom power, mainly because of the way the diaphram picks up sound (condenser mics pic up sound in a narrower area around the mic, yet can pick up distant sounds somewhat better). It earned the name phantom because it is invisible to other balanced (non-condensing, etc.) mics that don't need the extra power. A tech section would make it easier on most of us, because most of the important questions get lost in the typical whuz you're fav song or need lyrics plz questions that flood the section.

Q:Suppose load is 100KW, length 50m, how to calculate cable size. If we know current Is any easy mathod to calculate cable size.

rated current = 200 amp

Q:Opened the inside. Next to fuse, it says 8A 125VPower cable says it is 7A 125Vdevice doesn't not work. Could this be the problem?Not sure if the power cable is the original.

Did you check to see if the fuse was blown? Non- operation can be caused by fuse deterioration over time, in relatively heavy current situations. However usually, a blown fuse is indicative of more serious problems, which will not be rectified by replacing a blown fuse. A replacement would just blow again. The power cord/ fuse markings are irrelevant, they're fine. They are there to ensure any replacements are fit for the purpose they were intended for.

Q:I have a desktop PC that when turned on the fans works but it won't beep or display anything on screen. But after I unplug both motherboard power connectors and plug them back in, the PC stats working normally, why is that? Oh, and I tried disconnecting only the external power cable, no luck.

Its a trick that always seems to work this is because when you disconnect the motherboard it shuts down and it cant process any data, therefore when you plug it back in and it starts working again it starts from scratch and all the data before was forgotten. As this is very helpful to people what they don't realize is that every time you do this you are not letting your motherboard finish processing the information which can lead to long term damage.
