A delta connected load of 10 Ω per phase is fed from source voltage 230 V through a three-phase voltage source inverter in 120o mode. Let P1 be the total power in this mode. Another star-connected load of 10 Ω per phase is fed from source voltage 230 V through a three-phase voltage source inverter in 180o mode. Let P2 be the total power in this mode. Then the ratio P2 : P1 is:
1
9 : 4
2
3 : 2
3
4 : 9
4
2 : 3
