On what actually does ampere depends, thickness of wire or number of turns of wire or what else? Electrical
Higher current requires lower resistance in order to prevent heat buildup in wires. Multi-strand wires are not suitable for higher amperage applications. Stranded wires have higher resistance and insulating air pockets, which will cause them to heat up with increased current.. possibly to the point of melting insulation and/or causing fire hazards. Some stranded core wire uses material other than copper to cut costs, which further increases resistance. Large diameter solid core copper wire is the standard solution. They offer lower resistance and better heat handling ability. The trade-off is less flexibility and lower durability in moving or reuse situations.
ampere depends on the number of turns..........
Your okorder /... and get ohms/1000 ft for the size of wire you select. Also check fusing current while you are there. Eg, #30 has 105 ohms/1000'. So if you have 10' of wire, it's resistance would be 105/100 = 1.05 ohms. Once you have the resistance, use ohms law and the voltage applied to calculate current. For 12 volts, I = 12/1.05 or 11 amps. Fusing current is 10 amps (which is in the open, not in a coil) so you need more length or thicker wire. For AC, and coils, you need more complicated calculations.
