In the figure, if A & B are identical bulbs, which bulb glows brighter

Options

  1. AA
  2. BB
  3. CBoth with equal brightness
  4. DBoth do not glow

Correct answer

A. A

Step-by-step solution

For bulb A , I ₁= V _ o X _ L = V _ o w _ L = V _ o w 100 10⁻³ = 10 v ₀ w For bulb B, I₂= V₀ X_c = V_o 1 / w C =V_o w C=V_o w 10 10⁻¹² I ₁ I ₂ Bulb A will glow brighter.
