The resistance of 1 mm (diameter) solid copper is about 21.8 ohms per kilometer.
That's 10.6 ohms in 500 meters.
When 230 mA flows through 10.6 ohms, the voltage drop is
I · R = (.230)x(10.6) = 2.438 volts.
The voltage of the supply is irrelevant.
This is a voltage drop question. To answer this question a voltage must be given.
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.

Incorrectly calibrated meters.
Since you're only going 6 meters as your distance the voltage drop will not be a significant issue and you can use #12 AWG that is rated for 20 Amps
To create a scale drawing that measures 20 meters by 15 meters using a scale of 1 cm to 5 meters, you would need to draw a rectangle that is 4 cm by 3 cm. Each centimeter on the drawing represents 5 meters in real life, so 4 cm would represent 20 meters and 3 cm would represent 15 meters.
Voltage can kill a person even if you are only meters away.
The voltage drop in a 6-meter length of 16 mm² copper wire carrying a 40 Amp load can be calculated using Ohm's Law and the wire's resistance. Copper wire has a resistance of about 0.000133 ohms per meter. The voltage drop can be found using the formula Voltage Drop = Current x Resistance x Length. Therefore, the voltage drop in this scenario would be approximately 0.32 volts.
any where across where you think there is voltage present
A meter is a unit of metric measurement. A square meter is like drawing 4 meters to make a square.
in the short circuit test we applied supply voltage on L.V side and short circuit the H.V side and connect the ammeter in H.V circuit to measure the short circuit current. with the help of s.c test we measure the copper losses in the transformers.
Well, honey, if the CN Tower is 550 meters tall in real life and you're using a scale of 1:11000 on your drawing, then you just divide 550 by 11000 to get the height in the drawing. So, the height of the CN Tower in the scale drawing would be 0.05 meters, or 5 centimeters. Hope that helps, sugar!
The speed of light in copper is approximately 1.97 x 108 meters per second.
A 2/0 AWG copper conductor will limit the voltage drop to 3% or less when supplying 65 amps for 150 metres on a 240 volt system.
To measure voltages and voltage drops
No. The speed of sound in copper is well below that.
It is usually required in electrical examinations to make calculations. Simple answer to a complicated calculation. Remember, take peak to peak voltage and multiply by .707, the result being average voltage. This is the voltage that electrical test meters read.
