Answer:
answer should be 25 ohm
Given : Circuit
each of the resistors in the diagram has a resistance of 12 ohm
To Find : resistance of the entire circuit
5.76 Ω
25 Ω
48 Ω
120 Ω
Solution:
Lets Divide it in 4 block of resistance in series
R = R₁ + R₂ + R₃ + R₄
first three resistance are in parallel
1/R₁ = 1/12 + 1/12 + 1/12
=> 1/R₁ = 3/12
=> R₁ = 4 Ω
next two resistance are in parallel
=> 1/R₂ = 1/12 + 1/12
=> R₂ = 6 Ω
next 4 resistance are in parallel
=> 1/R₃ = 1/12 + 1/12 + 1/12 + 1/12
=> R₃ = 3 Ω
R₄ = 12 Ω
R = R₁ + R₂ + R₃ + R₄
= 4 + 6 + 3 + 12
= 25 Ω
resistance of the entire circuit is 25 Ω
