Question

Resistance across AB=?​

Answer 1

Answer:

BC and AC are in series connection so

Total series=3ohm+3ohm

total resistance in series=6ohm let it be

let it be R'

R' and AB are in parallel

so

1/Rt=1/R1 +1/R'

1/Rt=1/3+1/6

1/Rt=(2+1)/6

1/Rt=3/6

1/Rt=1/2

Rt=2

so resistance across AB=2ohm

please mark me as brainlist it is too important for me
