A delta connected load is supplied by a three-phase 480 V source. The delta current flowing from phase-c to phase-a was measured to be: Ibc= 25 ∠ - 120° A_RMS

Determine the equivalent wye impedance of the load.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.
