c) 1 on the 10. In Figure 2, we have two equivalent balanced circuits: one is $\Delta$ and one is Y circuit. What is the relationship between $Z_\Delta$ and $Z_Y$ a) $Z_\Delta = Z_Y/3$ b) $Z_Y = Z_\Delta/3$ c) $Z_Y = Z_\Delta$ 11. In the balanced $\Delta$-load, we measure the line current $I_\Delta$ and get the value 4A. What is the value of the line current $I_Y$ in the equivalent Y circuit? a) 4 A b) $4\sqrt{2}$ A c) $4\sqrt{3}$ A d) 5 A [Hint: we are talking about two equivalent circuits] 12. What is the most appropriate statement? a) In order to correct the power factor, we add a capacitor in series with the load. b) In order to correct the power factor, we add a capacitor in parallel with the load. 13. Please name the four assumptions of the ideal transformer Assumption 1:. Assumption 2:. Assumption 3:. Assumption 4:. 14. Which statement is correct? Please read them carefully. a) The instantaneous power of a three phase AC system is constant b) The instantaneous power of a balanced three phase AC system is constant c) The instantaneous power of a single phase AC system is constant d) Both single phase and three phase AC system deliver constant power
