Marks: +1, -0

Three equal impedances are first connected in delta across a 3-phase balanced supply. If the same impedances are connected in star across the same supply

phase currents will be $1/3$ of the previous value.
line currents will be $1/3$ of the previous value.
power consumed will be $1/3$ of the previous value
power consumed will be 3 times the previous value

Solution:

Three equal impedences are first connected in delta across a 3.phase balanced supply. If the same inpendence are connected in star across the same supply, then power consumed will be

1/3

of the previous value.
