www.csgnetwork.com/wiresizecalc.html says #3. (Though that seems a bit pessimistic, you might want to check another table) Remember when using this calculator that your total circuit length is twice the run of your wire (feed & return).
The minimum size conductor needed based on a 3% Voltage Drop for a 120 volt single phase service is 2/0 copper or 4/0 aluminum. It does not take into consideration other factors such as minimum ampacity based on the National Electric Code Table 310-16. ( Allowable ampacitys of conductors ). Consult The National Electrical Code for further details. For further information search for "Voltage Drop Calculator".
It is considered a 120 volt circuit. You will have a voltage drop of 4.89 volts if you use AWG #12. Unless you are going to be using sophisticated electronic equipment in this area AWG #12 will be fine to use. Otherwise use AWG #10 on a 20 amp breaker.
To answer this question a voltage is needed.
I would recommend AWG #12 on a 20 amp breaker.
Use 2/0 AWG.

Ohm's Law states Volts = Amps x Resistance. You would need to apply 600 volts across 3 ohm load to have 200 Amps flow in circuit. Not sure what you are really asking and why you mentioned 2 gauge.
Please rephrase your question. The electricity required for your pump is 230 volts.
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.
10 AWG copper.
Wire sizes are governed by the amperage the wire is to carry. To answer this question the load current is required.
30 amps.
12 volts
It depends on how much current it's putting out. An inverter rated at 800 volt-amperes can deliver 220 volts at 3.636 amperes, or it can deliver 110 volts at 3.727 amperes.
If the 12V source can deliver 100 Ampere, then yes. If it can't, then no. (remember watts / volts = amps)
LM105 series are monolithic voltage regulators, basically about 4.5 volts output, but which can be configured to deliver up to 40 volts.
Volts represents difference of potential and nanometers are distance. There is no coorelation.
