Chapter 11, Problem 21P

a)

To determine

Find the Y-connected equivalent circuit.

b)

To determine

Verify that the Y-connected equivalent circuit delivers the same open-circuit voltage of $\Delta$-connected source.

c)

To determine

Calculate the line currents $I_{\text{aA}},I_{\text{bB}},\mathrm{and},I_{\text{cC}}$ with the $\Delta$-connected source.

d)

To determine

Calculate the line currents $I_{\text{aA}},I_{\text{bB}},\mathrm{and},I_{\text{cC}}$ with the $Y$-connected source.
