Answer :

1. R₂ and R₃ are in series :

→ R₂₃ = R₂ + R₃

→ R₂₃ = 8 + 4

R₂₃ = 12Ω

2. R₂₃ and R₄ are in parallel :

→ 1/R₂₃₄ = 1/R₂₃ + 1/R₄

→ 1/R₂₃₄ = 1/12 + 1/12

→ 1/R₂₃₄ = 2/12

R₂₃₄ = 6Ω

3. R₂₃₄ and R₁ are in series :

→ R = R₂₃₄ + R₁

→ R = 6 + 6

R = 12Ω (Equivalent resistance)

Net current flow in circuit :

⭆ V = I × R

⭆ I = V/R

⭆ I = 12/12

I = 1 A

Voltage drop across R₁ :

➠ V = I × R₁

➠ V = 1 × 6

V = 6 volt

Therefore potential difference across parallel connection will be 12-6 = 6V

Current flow in first branch :

Equivalent resistance of first branch is 12Ω.

⭆ 6 = I₁ × R₂₃

⭆ 6 = I₁ × 12

I₁ = 0.5 A

Current flow in second branch :

⭆ I = I₁ + I₂

⭆ 1 = 0.5 + I₂

I₂ = 0.5 A
