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
1
phase currents will be \(\frac{1}{3}\) of the previous value
2
line currents will be \(\frac{1}{3}\) of the previous value
3
power consumed will be \(\frac{1}{3}\) of the previous value
4
power consumed will be 3 times the previous value
