AWG 10 guage.
10 GUAGE
8 AWG copper.
8 ga
Number 10 thnn copper wire.
If this question is asking about voltage drop, to size a wire, a voltage is needed.
A #10 copper conductor with an insulation rating of 90 degrees C is rated at 30 amps. A 40 amp circuit would need a #8 wire. To do a voltage drop calculation for a distance of 65 feet, a voltage of the circuit must be stated. Depending on the answer obtained from the calculation you might have to jump up one more size to #6.
Cannot answer this question. Will need to know the voltage and amperage of the circuit. Also need to know the application i.e. is it a lighting circuit or a motor circuit?
8 AWG copper.
AWG 2/0 copper wire.
8 ga
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
Depends on the size of the circuit which you did not list.
No. The wire size is dependent on the circuit protection. If the circuit uses a 20 amp breaker you need to run 12 AWG wire on all devices connected to that circuit.
Number 10 thnn copper wire.

Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.
