In the given circuit, the current in 8 resistance is 1.5 ~A . The total current (I) flowing in the circuit is

Options

  1. A5 A
  2. B4.5 A
  3. C3 A
  4. D5.5 A

Correct answer

D. 5.5 A

Step-by-step solution

I ₁=1.5 ~A , R ₁=8 P.D. across R ₁=1.5 8=12 ~V R₂=3 ; R₂ is in parallel with R₁ and hence P.D. across it is also 12 ~V . I ₂= 12 3 =4 ~A Total current I = I ₁+ I ₂=1.5+4=5.5 ~A
