About plus and minus ten percent. That makes it 108 minimum and 132 maximum volts.\n\nMost appliances are designed to expect this range.

The above answers about using a voltage regulator sound ok.  Just make sure to check out the regulator's data sheet so that it can safely regulate what DC voltage you are giving it (though with this 12V case you shouldn't have a problem).\n\nAlso, when a battery is rated at 12V, 30A the battery doesn't necessarily output 30A at all times; that is just a full load rating given for safety reasons (don't want to overload the battery).  The battery is a constant voltage source so you can certainly have a load that pulls much less than 30A.\n\nWidth of wire?  You shouldn't be too concerned with this at these low voltages.  Just use breadboard type wire (around 22 AWG I believe).\n\nAlso, one final comment from me... why use a car battery when you can use a more convenient source of DC voltage?  If you want something that can conveniently power your IC's try one of those nifty AC/DC plugs that charge cell phones and the like.  They are rated in various output voltages and can surely supply all the current your IC's will need.  Just cut off the DC plug end and strip the wire.  Boom, now you have DC voltage for your breadboard supply terminals or whatever.

If you are referring to electric clocks (works by a electric moter turning gears) and not electronic digital clocks, you should check your AC voltage throughout your house. It is probably too high. You can buy inexpensive multimeters at radio shack or most hardware stores.  If you are running too high (or too low), you should contact your electric company immediately, as you can also damage your appliances and electronic equipment.  I believe the acceptable range is from 115 to 125 volts.

480 VAC is produced as a 3 phase power source. Widely used here in the USA for industrial applications.\n\nThis voltage is not typically considered single phase, it is Line - Line. The 480VAC is transformed into 120VAC/220VAC for typical control circuits after it enters a control cabinet. The control Xfmr uses 480VAC line-line on its input.\n\nThis voltage to earth ground is not 480VAC, it is 480V/sqrt(3) = 277VAC.\n\nCheck out the 3 Phase power distribution below:

No, but some at the higher elevation have fireplaces and small electric heaters, When I lived in Hawaii the cars did't even have heaters and the walls in the houses were single wall construction and all the wireing and plumbing was exposed

Most house circuits are rated at 15 amps and the units you have found that list 115 volts, 15 amps are likely designed for such circuits.  That said, you must consider the total amps of other loads on the same circuit which may serve several other wall outlets, etc.  It is not a good idea to run other major units such as TV's or refrigerators on the same circuit serving your air conditioner.  Perhaps you can share the circuit with a clock or small lamp.  The air conditioner may draw maximum amps only during startup of the compressor (you can hear it groan).  If the circuit trips, shed other loads.  Avoid using extension chords for the air conditioner (even heavy duty chords increase voltage drop at the plugs).  One neighbor discovered that his house voltage was often lower than it should be and the power company added a booster for him.  Low voltage draws more current (amps).  A qualified electrician may be able to upgrade your circuit to 20 amps, depending on the house wiring, to avoid trips.  Good luck.

E = hf applies to light, not electricity.\n\nThe power consumed by AC current is assessed by the root mean square, which is equivilent to the peak amplitude divided by radical 2.  The frequency doesn't factor into the matter.

the input has to be the same unless you plan on plugging it into something other than a regular household outlet in the US.  the input is what it expects from the outlet you plug it into.\n  the output has to be 12V.  or else you might break your appliance.  the amps on the output can be greater than 600mA.  not less.  if your adapter is say 1000mA (1A) it has the capability of providing the 600mA your appliance needs, but if you have a 400mA adapter, it won't be enough.

What's to know?\n\nIt's the typical offset voltage, or DC component of the output.  The signal is AC.

Kapalua. It's not as warm as Lahaina or Kaanapali and it has nice ocean breeze. In most locations there you won't even have to use your air conditioning at all. Lahaina gets hot.
