40W, 100W and 200 W bulbs are connected with a source of 200 V ratings of all bulbs are also 200V. Now, they are connected in series, then which bulbs will glow more:
Text Solution
Verified by ExpertsThe correct answer is:
C
Resistance R = 
R ∝ 
So, the resistance of 40 watt is maximum, heat produced H ∝ R
heat produced in 40 watt bulb will be maximum, so it will allow more.
