Geometry of Three Phase Electricity Using Dr Geo (png image file)

Geometry of Three Phase Electricity Using Dr Geo (png image 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” (blue) has three equal spokes and the “Delta” (red) 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.The data file for Dr Geo is also on i2geo.net as Geometryofthreephaseelectricity.drgeo
