Answer 1

Step-by-step explanation:

=> Above two 10 ohm resistors are in series

=> Then R1 = 10+10 = 20 ohm.

=> Now this R1 is parallel with middle 10 ohm.

=> Then R2 = (R1*10)/(R1+10)

=> R2 = (20*10)/(20+10) = 200/30 = 20/3 ohm.

=> now R2 and remaining two 10 ohm is in series

=> R'= R2 + 10 + 10

=> R'= 20/3 + 20

=> R' = (20+60)/3

=> R' = 80/3
