Amotor operates with the following phase currents: phase a = 73.8 amperes, phase b = 68.5 amperes, and phase c = 64.4 amperes. motors should not be operated above a 10% current unbalance. calculate the maximum percentage phase unbalance for this motor.

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
