Geometry of Three Phase Electricity (Dr Geo geometry file)

Electricity is useful, powerful and potentially dangerous. Mathematics is useful in understanding it. Compass and straightedge construction can be used to represent the “Y” and “Delta” of three-phase electricity. The “Y” has three equal spokes and the “Delta” is an equilateral triangle. What is the ratio of the length of a line in the "Delta" to the length of a line in the "Y"? This diagram also represents the three cube roots of unity (1) in the complex plane. File type drgeo for Dr Geo dynamic geometry software. A png image of this construction is on as Geometryofthreephaseelectricity.png
