NEET2019PhysicsAlternating CurrentActual
In a transformer number of turns in primary circuit is 500 and in secondary circuit number of turns is 10 . The load resistance is 10 and voltage of secondary coil is 50 ~V . Then find the current in primary circuit.
Options
- A0.2 ~A
- B0.3 ~A
- C0.4 ~A
- D0.1 ~A
Correct answer
D. 0.1 ~A
Step-by-step solution
Given, N₁=500, N₂=10, R_L=10 ₂=50 ~V Current in the secondary circuit is aligned & i₂= V₂ R_L = 50 10 =5 ~A & i₁ i₂ = N₂ N₁ i₁ 5 = 10 500 i₁=0.1 ~A aligned
