Answer 1

Answer:

hey mate here is ur ans

Explanation:

let the resistance from loitnt A TO B

R1, R2, R3, R4

Let R5 is resistance which is below

as we see R2and R3 are in series

so

R' = R2+R3 = 18 ohm

and then see R' and R1 are in parrelel so

R" = R'R1/R'+R1 = 6 ohm.

then we see R" and R5 are in parrelel the

R"' = R"R5/R5+R" = 1 ohm

and then R"' and R4 are in series then

Req = R"'+R4 = 2ohm

2. is correct

hope it help u
