Question

help me guys

Answer 1

each reisistance are 1 ohm

Answer 2

r u sure @Pompeii00
my concern is do i need to use delta -wye?

Answer 3

what do u want to find ?

Answer 4

resistance AC,

Answer 5

DE and AG

Answer 6

well Rde is easy, there are only 2 resistors between them, so
Rde = 1|| 1

Answer 7

next easy resistance is Rcf
1, 1 and 1/2 will become in series, and that combination is in parallel with 1

can you visualize this ?
Rcf = 1 || (1+1+1/2)

Answer 8

5/7 or .714 ?

Answer 9

after that, the wye at ABCG needs to be converted to delta.
