In the given figure R ₁=10 , R ₂=8 , R ₃=4 and R ₄=8 . Battery is ideal with emf 12 ~V . Equivalent resistant of the circuit and current supplied by battery are respectively :

Options

  1. A10.5 and 1.14 ~A
  2. B12 and 1 ~A
  3. C10.5 and 1 ~A
  4. D12 and 11.4 ~A

Correct answer

B. 12 and 1 ~A

Step-by-step solution

Here R ₂, R ₃, R ₄ are in parallel aligned & 1 R ₂₃₄ = 1 R ₂ + 1 R ₃ + 1 R ₄ & R ₂₃₄=2 aligned R₂₃₄ is in series with R₁ so aligned & R _ eq = R ₂₃₄+ R ₁=2+10=12 & i = 12 12 =1 Amp aligned
