30 bulbs are connected in series if one bulb is fused and the remaining 29 bulb are joined in series and connected to the same supply the light in the room will be a) increase b) decease c) remain same

c)remain same is answer
Sanjayuma:
why
can explain it
The light will increase. If the voltage remains same, then the power available is P = V^2/R, where R is the resistance of the series. When one bulb is removed, the resistance of the series decreases and hence the power output will increase.

increased is the ans uma
do u need explanation
The light will increase. If the voltage remains same, then the power available is P = V^2/R, where R is the resistance of the series. When one bulb is removed, the resistance of the series decreases and hence the power output will increase.
r u sure
A series circuit's principle characteristic is that it has only one path in which its current can flow. Opening or breaking a series circuit at any point causes the entire circuit to "open" or stop operating. For example, if even one of the light bulbs in an older-style string of Christmas tree lights burns out or is removed, the entire string becomes inoperable until the bulb is replaced.
hence the answer is decrease
didn't u see the thing that the remaining 29 bulbs are connected again to the same circuit? so i am sure that the ans is increased
ok
No the answer is decreased
