Answer 1

The equivalent resistance of the circuit will be 10Ω

Explanation :

Starting from the back side the equivalent resistance of the circuit can be given as,

R = (R₆ + R₁₀) || R₉ + R₇ || R₈ + R₅ || R₄ + R₃ || R₂ + R₁

=> R = 12||6 + R₇ || R₈ + R₅ || R₄ + R₃ || R₂ + R₁

= 4 + 8 || R₈ + R₅ || R₄ + R₃ || R₂ + R₁

= 12 || 6 + R₅ || R₄ + R₃ || R₂ + R₁

= 4 + 4 || R₄ + R₃ || R₂ + R₁

= 8|| 8 + R₃ || R₂ + R₁

= 4 + 4 || R₂ + R₁

= 8|| 8 + R₁

= 4 + 6

=> R = 10Ω

Hence the equivalent resistance of the circuit will be 10Ω
