if 100W and 200W bulbs are connected in series to a supply
which bulb will glow brighter and why
Answer Posted / chaturbhuj poddar
If the rating of two bulbs be as (100W-220V) &(200W-220V)and be connected in series to the same d.c.voltage supply. then the value of current is same in both the bulbs. It can be seen that the resistance of 100W bulb is greater than the resistance of the 200W bulb. Hence, heat produced in 100W bulb is more than produced in 200W.Conclusion: 100W will glow brighter than 200W bulb.
