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.
Probably ok if the new supply can produce the required amount of current in amps.
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.
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.
Nothing will happen, you can go over 6.3v but never under......
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).

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 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.
