As I get the web search
The area of the primary or secondary Conductor measured as
= The current in the conductor / Current density of copper (ie,2.3)
if current is .23A
The area of the conductor = .23A/2.3A mm^-2 = 0.1mm^2 = selected wire is 27AWG
The my question is whenever the current is above 100 Ampere how to select the copper .?
because of for example Current = 100Amp
Area of conductor = 100/2.3 = 43.47mm^2 AWG 1 require it cannot wind what is option ?
