A balanced three-phase 208-V source supplies a balanced three-phase load. If the line current \(I_{A}\) is measured to be \(10 \mathrm{~A}\) and is in phase with the line-to-line voltage \(V_{\mathrm{BC}}\), find the per-phase load impedance if the load is

(a) Y-connected,

(b) \(\Delta\)-connected.
