AA batteries are probably used for a current of less than 1 amp so thin wire is fine, 0.5 mm-sqd or #24 wire would be ok.
Wire size is based on the amperage of the load. Without a load current this question can not be answered.
12 gauge
30 gauge wire is much "thinner" than 10 gauge wire. Hence, if you are using 10 gauge for an application requiring only 30 gauge, it will more than handle any current flow. However, if the application requires 10 gauge wire you cannot use 30 gauge wire.
The lower the voltage the larger gauge wire you will need to get the same power.
A. It's 240 volts & B. Wire size is a function of amperage. 12-gauge wire is used with 20 amperes or less. So, 12-gauge wire can be used with 120V/20A or 240V/20A. Keep in mind though that 240V in the U.S. has 2 live 120V lines so if you encounter a white wire, it's probably an unmarked live & should be repainted as black or better yet, red (to indicate the 2nd live wire).
Yes. It is abbreviated as AWG. For example, in residential wiring the size wire to use on a 15 Amp circuit would be 14 gauge or 14 AWG.
AWG is American Wire Gauge. Just as you would convert inches to any metric value you can follow the same process for wire gauge. Example: AWG 14 gauge wire is 0.0641 if you were to convert this to metric you would use 25.40 which is a conversion number for inches to mm. therefore 25.40 x 0.0641 = 1.628mm rounded would be 1.63mm
12 gauge
34 gauge copper wire will work but to use the 35 gauge copper wire is the best choice
Here's the formula for converting American (or Brown and Sharpe) wire gauge to millimeters:dn = 0.005 mm x 25.4 x 92 36-n/39With this formula, you can convert a wire gauge size to the diameter of the wire in millimeters. The dn is the diameter of the wire in millimeters, as you might have guessed, and the n in the exponent is the gauge of the wire you wish to find the diameter of.Wikipedia has a fine article on this. They have the formula for converting wire gauge to diameter as well as one for calculating cross-sectional area. They also explain where the formula comes from, if you're interested. The formula for converting from diameter to the wire gauge, the inverse of this formula, is also listed, as is a chart. A link is provided for you convenience. Another link is also provided to an online calculator that will let you just put in a diameter or a wire gauge and will do all the work for you. (Note that this calculator works in inches and not millimeters, so you'll have to make a conversion.)Improved Answer By Sandip Vikma :"Above original formula is difficult to calculate. So, you may use bellow derived formula to convert Gauge into MM".dn = 0.127 x 92 [0.9230769-0.025641026n]Where,dn = Thickness in MM.n = Thickness in Gauge.
The wire gauge in thin headphone cables is quite small. I have read of people rewiring their headphones using 12 Gauge wire. There are commercial cables that use 11 gauge. The thicker the wire the less the resistance up to a point. Many headphones use 22 or 24 gauge and it seems to work OK.
The cars computer is calibrated for a certain gauge wire. There is a small amount of leeway allowed. However use as close to original gauge wire as possible.
It is better to use 16 gauge or 14 gauge speaker wire for your home theater applications.
use a stronger wire for longer antennas...the gauge may not be as important as the strength if you string it outside.
A domestic D/W uses 14 gauge wire.
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
Use 8 gauge wire.
I would recommend you use 1/0 gauge
