Discussion: 1. Did your experimentali results verify the equivalence between the delta and star connections? (Compare the voltage and the currents in both cases). 2. The sum of the three voltage for Y or A (Vs. Voc. Va) must be equal to zero .Why ? Did your readings of the voltages verify this condition? Prove that. 3. Did the power delivers from (DC power supply) is changed after using the conversion from A to Y. Prove that? 4. When we have three equal resistors for a Y connection prove that (the value of each resistor of the delta is equal to three times the value of any resistor of the Y).
