What will happen if two electric bulbs of 25 W and 100 W both rated at 220 V are connected to the main 220 V supply in series?

No,25 W` bulb will fuse. From this , it is clear that voltage across the 100W bulb (=88V) is lesser than specified (220V), while across the 25Wbb̲(=352V) is greater than specified (220V), so the 25W bulb will fuse.

When a 25W 220V bulb and a 100W 220V bulb are connected in series then which bulb will glow brighter?

Since the bulbs are connected in series, the current through each bulb will be the same. Thus the power dissipated will be proportional to the resistance of each bulb. The bulb having more resistance will dissipate more power. Thus $25\;{\text{W}}$ bulb having more power will glow brighter.

When a 60w 220V bulb and a 100W 220V bulb are connected in series then which bulb will fuse?

The resistance of the bulb is given by R=V2/P. So the resistance of 60 W bulb is more than the resistance of 100 W bulb. When they are connected in series the current through both bulbs is same. Hence 60 W bulb will be more brighter because P = I2R.

What is the ratio of resistance if two bulbs have rating of 40w 220V and 20w 110v?

The ratio of their resistance is 4.

What will happen if two electric bulbs of 25w and 100w?

both the bulbs will fuse.

Which bulb will fuse first in parallel?

In a series combination, the bulb with a higher resistance will handle more voltage and hence will be the first to fuse. Therefore, the third option is also correct.

What happens when two bulbs are connected in series?

In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness. In parallel, both bulbs have the same voltage across them.

What will happen if two electric bulbs of 25w and 100W?

When two bulbs a 40 W 220 V and B 60 W 220 V are connected in series which bulb is brighter?

the bulbs in series have the same current flowing through both of them. Therefore the bulb with the higher resistance and with the same current will have the higher power and hence higher brightness.

What is the ratio of the resistance if two bulbs?

The correct answer is 1 : 2. We are given the ratio of the resistance of the two bulbs, let it be R1: R2 = 1: 2, the bulbs are connected in series, so the same amount of current will pass through both of the bulbs.

Which of the bulbs will fuse to a 440V supply?

Two electric bulbs marked 25W 220V and 100W 220V are connected in series to a 440Vsupply. Which of the bulbs will fuse? When connected in series, the voltages divide in them in the ratio of their resistances. The voltage of 440 V devides in such a way that voltage across 25 w bulb will be more than 220 V. Hence 25 w bulb will fuse.

Are 25W and 100W bulbs connected in series across 220V?

Two electric bulbs, rated at (25 W, 220 V) and (100 W, 220 V), are connected in series across a 220 V voltage source. If the 25W and 100 W bulbs draw powers P1 and P2 respectively then?

What is the ratio of power dissipation in two electric bulbs?

Two electric bulbs P and Q have their resistance in the ratio of 1: 2. They are connected in series across a battery. Find the ratio of the power dissipation in these bulbs.

How many Watts Does It take to light two bulbs?

Two electric bulbs, one of 220 V -40 W and other of 200 V – 100 W are connected in house wiring circuit. A student claims that the second of two light bulbs in series is less bright than the first because the first light bulb uses up some of the current.
