Power is the product of amps x volts, it has nothing to do with wire size.
4 AWG wire is much thicker than 18 AWG wire, which means it can handle higher electrical currents and therefore can deliver more power. The power difference between the two wire sizes will depend on the specific application and the amount of current being carried.
4 Gauge wire is larger in diameter than 6 Gauge wire.
The recommended gauge for 18/4 thermostat wire in a residential HVAC system is typically 18 AWG (American Wire Gauge).
No, code does not allow that.
AWG # 6 copper or AWG # 4 aluminum
Base = 18, Power = 4
the lower the number, the larger the wire. 0 AWG is larger than 4 AWG More information: The above answer is correct but I wish to add more information. What you are calling 0 AWG is usually written as 1/0 and called "one ought". From there the numbers get larger: 1/0, 2/0 (read "2 ought"), 3/0, and 4/0. From there wires are written in there MCM size or kcmils (kilo-circular-mills) which stands for thousand circular mills, the same as MCM. That's a lot of useless information unless you are a competent electrician. I just wanted to clarify that 0 AWG is commonly called 1/0, or "one ought."

For a 100 amp service located 160 feet from the power pole, it is recommended to use 2 AWG copper wire or 1/0 AWG aluminum wire to ensure proper voltage drop and safety. Be sure to consult with a licensed electrician to determine the specific requirements for your installation.
10 AWG wire will have less resistance per foot and therefore you can have longer runs with 10 AWG than 12 AWG without as much loss of signal. Additional to loss of signal there is a need to maintain a low impedance driving the typical speaker with its 4 ohm or 8 ohm coil resistance, to avoid frequency-distortion. A guide rule is that the speaker cable should have a total resistance around 1% of the speaker resistance (or less). On that basis, for 5 yards of speaker cable for a 4 ohm speaker the wire size would be 4 sq. mm (11 AWG) or for an 8 ohm speaker 2 sq. mm (14 AWG). <<>> Using the above formula of 1% of the speaker resistance the above answer is not correct. For a 4 ohm speaker at 1% is .04 ohms. The resistance of #12 wire is .001588 ohms per foot. This will allow you to run 25 feet and still stay within the parameters. For a 4 ohm speaker at 1% is .04 ohms. The resistance of #10 wire is .00100 ohms per foot. This will allow you to run 40 feet and still stay within the parameters. You can see, what the first answer states is correct.
A 4-4-4-6 copper wire refers to its gauge size, with the first three numbers representing the American Wire Gauge (AWG) sizes of the conductors and the last number indicating the size of the ground wire. In this case, the wire has four 4 AWG conductors and one 6 AWG ground wire.
In the expression 18 to the 4th power, the exponent is 4. An exponent indicates the number of times the base number (in this case, 18) is multiplied by itself. So, 18 to the 4th power means 18 multiplied by itself 4 times, which is equal to 104,976.
