Probably ok if the new supply can produce the required amount of current in amps.
Yes, you can use a 10 amp 125 volt power cord on your computer with a 6 amp 125 volt input. The power cord's amp rating represents the maximum current it can handle, so it is suitable for your computer's lower amperage requirement. Just ensure the voltage matches to avoid any potential damage.
It is 40 volt-amps, which is 40 volts at 1 amp, or 10 volts at 4 amps, etc. On an AC supply it could be equal also to 40 watts, or some lesser number of watts depending on the power factor of the load.
In the US, Canada and other countries running a similar 60 Hz power supply service, household lighting and low-power appliances run at 120 volts plus or minus 10%. So the actual voltage supplied can change betwen 108 volts and 132 volts and would still be within proper limits. (To get the actual figures for your locality it is best to ask a local licensed electrician or your local electricity supply company.) But please note the above answer is for low-power appliances only, not clothes dryers. Dryers have to draw a much higher current or amperage than your normal 120 volt socket outlets can supply. For more information on installing a new breaker, circuit wiring and the correct socket outlet to suit a 120 volt dryer, please see the answers to the Related questionsshown below.
To power ten 12 volt 10 watt lights, you would need a transformer with a total output of at least 120 volts and 100 watts.
There is no standard Amperage for a 220 volt outlet. It all depends on the wires/conductors used to supply the outlet and the breaker that protects it. You can have an outlet with: 15 amp, 220 volt 20 amp, 220 volt And so on.....
If the power supply has a 5 volt tap on the secondary side of the transformer, yes. If there is no tap and the secondary side of the power supply is only 10 volts then no, you can not substitute the higher voltage unit.
Using a 10 volt power supply for a 9 volt keyboard is not a good idea. The higher voltage will cause damage to the keyboard, burning it out and making it useless.
Yes, a 120 volt light can work on a 110 volt power supply without any issues. The difference of 10 volts will not significantly impact the function or performance of the light.
No, it requires a 180 Volt supply. Most appliances work +/- 10%, in this case 162 Volts to 198 Volts. I would question whether your appliance is really 180 Volt. No country uses this as domestic supply, it is usually 110V or 220-240V.
the possibility is the will get burnt
As Dave says there is no obvious reason to do so. However if you put a 200mA fuse or circuit breaker in series between the supply and the load you will protect the load from pulling more than 200mA from the supply should the load malfunction. That way the load is protected from damaging itself (if that was your concern).
+10
This DC voltage variation is typically used in controllers; zero (o) is stop and 13 Volts is maximum. More typical is zero to 5 volt or zero to 10 volt DC control.
A 10 ohm resistor across a 20 volt source has 2 amps flowing through it. A 20 volt source providing 2 amps is producing 40 watts. Voltage is Resistance times AmperesWatts is Voltage times AmperesAlternative AnswerDivide the square of the voltage by the resistance.
Yes you should be fine. As long as it fits in the computer, you're fine. Replace the old with the new one but keep the old one in case the new one doesn't work! 300 watts is fine for replacing something smaller. You should run only one power supply at a time. What this means is that you should replace the 185 Watt supply with the 300. Having 2 separate power supplies creates the possibility of having slightly different values for ground, +5V, and +12V DC. This can cause problems with all of your computer components. Don't use both, replace the old one with the better one. <- There are some motherboards that REQUIRE two power supplies, but you probably don't have one. They're server mb's, and the reason you use dual supplies is, if one supply dies the computer uses the live one and notifies the system operator "one supply just cooked, get me a new one pls." This eliminates a point of failure. If you've got one of these mb's, both supplies have to be the same: two 300w, two 750w, whatever. Really, though, with the amount of juice some of these new video cards pull, I wouldn't even consider installing a 300w power supply in anything except a server, a lot of which are "headless"--they don't have video outs, you control them over your network. Go with at least a 500w supply, and if you might have the need for a dual-head system--two monitors are GREAT, don't let anyone tell you different--go with a 1200w supply.

A 9 volt battery is only going to supply about 50 milli-amps of current. Remember the size of the battery and how it is constructed. It is literally a pile of 1.5 volt cells stacked together to make a 9 volt package. Those cells are just so big, and have limited current as a result For your question, get the 6 to 12 volt AC operated power pack. You'll be dealing with the low voltage side, and barring a failure of the device, your load will never see the 110 volt supply side. To get the kind of current that you need from 9 volt batteries, figure of 50 mA (milli-amps) each, divided into the current the project needs. If it is 500 mA, then you need 10, 9 volt batteries. They are not going to last very long either. So, for your needs and desires, go get the AC operated power supply, just fuse it at a bit less than what you need it to produce in terms of current draw.
