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.
What will happen if two electric bulbs of 25 W and 100 W both rated at 220 V are 1 connected to the main 220 V supply in series?
No,
25 W` bulb will fuse

When 25 W and 100 W bulbs bulbs are connected in series which bulb are more glow?
so, power dissipated is inversely proportional to power rating of the bulbs. so, power dissipation will be more in 25 W bulb. hence,
25 W bulb will glow brighter
.
Which has higher resistance between 25 W bulb and 100W bulb at same potential?
Lower the resistance higher the power. Hence
25w
has the highest resistance.
When a 25W 220V bulb and a 100W 220V bulb are connected in parallel then which bulb will glow brighter?
Now more current will flow in the bulb which has less resistance which is
100W bulb
this time which means 100W bulb dissipate more power than 80W bulb (P=I
2
R) where current and resistance are directly proportional to the power. Hence, 100W bulb will glow brighter in a parallel circuit.
When electric bulb is rated 220v and 100W?
Solution. R = 220
2
/100 Ω =
484 Ω
. This is the resistance of the bulb. When V = 110 V, power consumed = V
2
/R = 110
2
/484 = 25 W.
What will happen when 40w 220v lamp and 100W 220v lamp are connected in series across 440v supply?
100 watt lamp will fuse
.
Which bulb is more glow?
To find which bulb will glow brighter we need to find the power dissipation across each of them. From the relation P=(I*I) R since current is same we can say that power dissipation will be higher for the bulb with higher resistance i.e.
40W bulb
. Hence 40W bulb will glow brighter in series connection.
When a 60w 220v bulb and a 100w 220v bulb are connected in parallel then which bulb will glow brighter?
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
.
Which bulb will glow brighter 60w or 100w in series?
Answer: The bulb rated at
100 W will be brighter
. When both bulbs are connected to the rated voltage, they will dissipate the rated power. The brightness of a bulb depends on the power it dissipates, so the 100 W bulb will be brighter than the 60 W bulb.
Which has higher resistance 100w or 25W?
Thus, we observe that for minimum power, resistance will be maximum and vice-versa. hence, resistance of
25W bulb is maximum
and 100 W bulb is minimum.
Which will have higher resistance 50w or 25W?
Resistance R = V
2
/P, where V is the potential difference and P is the power in Watts. So, the more the power, the lower will be the resistance and vice versa. … Thus,
25 W bulb will have double the resistance
as compared to 50 Watt bulb.
Which has greater resistance a 100 watt bulb or a 60 watt bulb?
A 60-watt bulb
has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high.
When a 60w 220v bulb and a 40w 220v bulb are connected in series then which bulb will glow brighter?
Always, when two bulbs of the same voltage and different wattages are connected in series, the
lower wattage bulb
will glow brighter. … There is no question that the 40w bulb has a higher resistance than the 60w bulb; so the 40w bulb will dissipate more wattage and therefore be brighter.
What will happen if one of the bulbs is removed?
By removing one lightbulb, you’re
effectively replacing the bulb with an open switch
; as a result, there will be no current, and thus the other lightbulbs will go dark. This is why electrical components in buildings are wired in parallel.
Why do bulbs glow brighter in parallel?
Each bulb sees the full voltage when the bulbs are in parallel.
When a bulb gets more power, it will glow brighter
. The effective resistance of the circuit is reduced by the parallel combination of resistors. … It glows brighter.
