Question: Determine the base current and base impedance in a three-phase power system on the base of 50 MVA 3-ph and 11 kV LL , first

Determine the base current and base impedance in a three-phase power system on the base of 50 MVA_3-ph and 11 kV_LL, first using single-phase formulas and then using three-phase formulas, recognizing that both single-and three-phase formulas give the same base current and base impedance values per phase.
