Regarding the question of "Why isn't there voltage drop in a 240 volt system?"
The smart alex answer is "because no current is flowing." Only if no current is flowing can there be no voltage drop in any circuit.
All conductors, even supercondutors, have resistance and this resistance will produce a voltage drop when a current is flowing through the conductor(s).
240 volts is used over 120 (or 12 volts) because it reduces the current reguired for a fixed amount of POWER (watts). Therefore, the conductor size can then be reduced to reduce cost, size, weight or to improve flexibilty.

Is a voltage drop of 0.4 volts acceptable for a 12-volt system.?
A voltage drop of 0.4 volts in a 12-volt system represents a drop of about 3.3%, which is generally considered acceptable for many applications. However, the acceptability can vary based on the specific requirements of the devices being powered and the length of the wiring. For critical applications or longer wire runs, aiming for a lower voltage drop is advisable to ensure optimal performance and efficiency.
What size wire for 110 volt 20 amp circuit 700ft?
I would recommend no smaller than #8awg copper. This is derived by 8awg copper ampacity of 40 amps multiplied by 80% load rating to get 32 amps. Then calculating for voltage drop over this distance shows a drop of 5.9 volts or 2.5% which is negligible so not accounted for. So like i said no smaller than #8awg copper.
If a 240 volt system is only drawing 12 volts what is the probably wrong?
If a 240-volt system is only drawing 12 volts, the probable issue is a voltage drop caused by a poor connection, damaged wire, or loose connection within the circuit. Check for any loose or corroded connections, damaged wires, or faulty components in the system that could be causing the voltage drop.
How do you boost a24 volt system?
To boost a 24-volt system, you could use a boost converter or a voltage booster. These devices can increase the voltage output from a lower voltage source to the desired 24 volts. Make sure to select a boost converter that is rated for the input voltage and current requirements of your system.
Low voltage lights equivalent to 110 volt lights in watts?
To convert low voltage lights (e.g. 12 volts) to wattage equivalent to 110 volt lights, you would divide the voltage by 10. For example, 50 watts in a 110 volt system would be equivalent to a 5 watt bulb in a 12 volt system.
What is the correct wire size to install with a distance of 200 feet for a 100 amp single phase underground service?
This is a voltage drop question. A #1 copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 200 feet on a 240 volt system. Or a 3/0 copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 200 feet on a 120 volt system. In your question you sis not stipulate what the working voltage is.
Acceptable voltage drop for 3 phase 415 volt motor?
The voltage drop should not exceed 3% on a feeder or branch circuit.
What size wire for 110 volt 20 amp circuit 700ft?

Do you need a voltage regulator if you hook up a 12 volt light to a 24 volt system?
Hook a 12 volt light to a 24 volt system and the light will burn out in seconds. You need a step-down voltage converter to do this.
Is forward voltage drop of schottky diode more than tunnel diode?
Yes, the forward voltage drop of a Schottky diode is usually more than the forward voltage drop of a tunnel diode. A Schottky diode voltage drop is between approximately 0.15 to 0.45 volt. The interesting thing that makes a tunnel diode different from other diodes is its "negative resistance region" with a "peak current" around 0.06 volt and a "valley current" around 0.30 volt.
If a 240 volt system is only drawing 12 volts what is the probably wrong?
If a 240-volt system is only drawing 12 volts, the probable issue is a voltage drop caused by a poor connection, damaged wire, or loose connection within the circuit. Check for any loose or corroded connections, damaged wires, or faulty components in the system that could be causing the voltage drop.
What is the volt drop across a 10k resistor with a 5 volt supply?
If there is nothing else in the circuit, then the voltage drop across the resistor will be the full supply voltage of 5 volts. The size of the resistor does not matter in this case - it will always be 5 volts.
Is the voltage for 1956 Chevy truck 6 volt or 12 volt?
Originally it would have been a 6 volt system.
What wire size 240 volt 21 amps 150 foot run?
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
What voltage does a semi truck electrical system have?
12 volt
What is the proper voltage for 2008 Acadia?
It is a 12 volt system.
What do you use to check for line voltage sags?
Voltage drops need to be checked with a volt meter. Depending on where the drop is thought to be, the meter can be connected an wiring plugs to find where the drop is.
