A bulb of (25 ~W , 200 ~V ) and another bulb of (100 ~W , 200 ~V ) are connected in series with a supply line of (220 ~V ). Then

Options

  1. Aboth bulbs will glow with same brightness
  2. Bboth bulbs will get fused
  3. C(25 ~W ) bulb will glow more brightly
  4. D(100 ~W ) bulb will glow more brightly.

Correct answer

C. (25 ~W ) bulb will glow more brightly

Step-by-step solution

Resistance of 25 ~W , 200 ~V bulb R₁= (200)^2 25 Resistance of 100 ~W , 200 ~V bulb R₂= (200)^2 100 . Clearly, R₁>R₂ . H₁>H₂ . 25 ~W bulb will glow more brightly.
