10 gauge wire is the correct gauge for a 30 amp circuit.
<><><>
The length of wire-run should also be factored-in when deciding the correct wire size.
To get the right answers refer to the Wiring Codes or Regulations for your locality. (Town/State.)

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

A #10 wire with an insulation factor of 60,75 or 90 degrees C is rated at 30 amps respectively.
according to the nec code book at an ambient temperature of 30 degrees Celsius (86 degrees Fahrenheit) then a #10 wire will carry 30 amps. However, if the ambient temperature reaches over 86 degrees Fahrenheit, then the amperage of the wire should be reduced by a certain percentage to prevent overheating of the wire.
AWG#10 copper is the minimum for 30 amperes in a household circuit. If heating or cooling equipment is involved (e.g. electric dryer or air conditioner) I would spend a little extra and use #8.
A 30 amp circuit often requires 10 awg conductors but before you use that size it is wise to refer to the wiring tables in the NEC for the recommended wire size to use for the distance from the main breaker panel and the installation environment i.e. if in a raceway, in the open air, underground, etc. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

10 gauge but that's the max the wire is rated at and that is NMD90 or loomex
A #10 copper wire with an insulation rated at 90 degree C has a rating of 30 amps.
A #10 copper wire insulation rating of 90 degrees C is rated at 30 amps.
#10 copper wire is rated for 30 amps.
10 AWG in a home wiring situation.
length of run is 100'?
Yes, 12 AWG is good for 25 Amps if copper wire.If aluminum wire, then good for 20 Amps.
A 20 amp circuit with #12 gauge wire will work in any event but if the nameplate recommends a 15 amp circuit then #14 gauge wire on a 15 amp circuit is sufficient. In either case you will have a double pole breaker and your equipment may not require a neutral. Always run a grounding conductor.

Outlets are part of a "branch" circuit.

The thickness of copper telephone wires was/is specified by their weight per mile. 80 oz per mile is about 24 gauge in the USA
Power dissipation in a resistor, or any other type of load, for that matter, is measured in watts and calculated as volts times amperes. It does not matter if the resistor is in a series or a parallel circuit, so long as the volts and amperes in the calculation is for that one resistor. Obviously, volts and amperes is distributed amongst the components of a circuit, and series vs parallel can have a significant affect on that distribution, so you will need to calculate or measure them on a case by case basis.
12 gauge
This is a voltage drop question. To answer this type of question a circuit voltage and the circuit load amperage must be given to calculate an answer.
they are used for more power than a series circuit so you should use this one.
difference between p type and n type semiconducter materialAnswerInsulation is used to prevent a short current. To protect the circuit should a short-circuit fault occur is either a fuse or a circuit breaker.
#6 wire is good for 65 Amps as long as it is type THHN.
It is a resistive type of circuit.
