Thanks for the resources. The formulas under "Current, Amperes (I)" only are correct for DC and AC circuits with only resistance, or a power factor of 1. Common AC circuits have resistance and reactance, the result of these is impedance, and a power factor other than unity (1). If P equals power in watts; then "Single-Phase = P/(E times power factor)" and "Three-Phase = P/ (E line times 1.732 times power factor)".

I have been using the Mike Holt Free resources in teaching my IEC 1st year apprentice classes. From introduction to the NEC to Code changes. The Ohms law posters are also a huge hit with the class. Thanks for making teaching our next generation of Electricians a bit easier.
