99 Percentile Qs Bank for JEE MainPhysicsCurrent Electricity
In the circuit, E₁=E₂=E₃=2 V and R₁ and R ₂=4 ~W . Then the current flowing through E ₂ is
Options
- AZero
- BA from A to B
- C4 ~A from A to B
- D2 ~A from B to A
Correct answer
D. 2 ~A from B to A
Step-by-step solution
aligned & E_ e q = E₁ R₁ + E₃ R₂ 1 R₁ + 1 R₂ = E₁ R₂+E₃ R₁ R₁+R₂ = 2 4+2 4 42+4 =2 V & R_ e q = R₁ R₂ R₁+R₂ = 4 4 4 4 =2 & -E₂+i R_ e q -E_ e q =0 & i= E₂+E_ e q R_ e q = 2+2 2 =2 A aligned Hence, the current flowing through E ₂ is 2 ~A from A to B
