EE 203 Circuit Analysis: Practice Problems on three-phase systems IbB IBC 30° - 30° ►IAB aA A balanced three-phase A-connected load is fed from a balanced three-phase circuit. The reference for the b-phase line current is toward the load. The value of the current in the b-phase is 12/65° A. If the phase sequence is negative, what is the value of IAB? ICA 30° Icc
