c)remain same is answer

Sanjayuma: why

Sanjayuma: can explain it

JAZZ0619: 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.

Answered by JAZZ0619

increased is the ans uma

JAZZ0619: do u need explanation

Sanjayuma: r u sure

Sanjayuma: 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.

Sanjayuma: hence the answer is decrease

JAZZ0619: 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

Sanjayuma: ok

Iamabby0017: No the answer is decreased
