Algorithm (Workflow)

This function, AWG2mm, converts American Wire Gauge (AWG) to wire diameter in millimeters. It is part of the SolidGeometry library and was introduced in version 5.0.

Input Parameters

awg: The American Wire Gauge value. Default is 36 if not provided.
len: Optional cable length in meters. Default is 1 meter.
Ucc: Optional cable voltage. Default is 12 volts.
Isc: Optional cable current. If not provided, it is calculated using the formula I = Ucc / rmm.

Output

dmm: The wire diameter in millimeters.

Algorithm Steps

Retrieve the input parameters using the getfuncparams function. If parameters are not provided, use default values: AWG = 36, len = 1 meter, Ucc = 12 volts.
Define constants: AWG36 = 0.127 mm for the diameter of AWG 36 wire, and rcup = 0.0178 Ohm/mm² for resistivity.
Calculate the wire diameter dmm using the formula: dmm = AWG36 * 92^((36 - awg) / 39).
Calculate the cross-sectional area amm using the formula: amm = (dmm / 2)^2 * pi.
Calculate the resistance rmm using the formula: rmm = rcup * amm * len.
Calculate the current I using the formula: I = Ucc / rmm.
If Isc is not provided, set it to I.
Calculate the power W using the formula: W = Ucc * Isc.
If no output is requested, print the results using dbprintf:
- Print the wire diameter and cross-sectional area.
- If the length is not the default, print the resistance.
