A 100 W bulb `B_(1)` and two 60W bulbs `B_(2) and B_(3)`, are connected to a 250 V source, as shown in figure. Now `W_(1), W_(2) and W_(3)` are the output powers of the bulbs `B_(1), B_(2) and B_(3)`, respectively. Then

A

`W_(1)gtW_(2)`=`W_(3)`

B

`W_(1)gtW_(2)gtW_(3)`

C

`W_(1)ltW_(2)`=`W_(3)`

D

`W_(1)ltW_(2)ltW_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Voltage across bulb `B_(2)` will be less than that across `B_(3)` `rArr` `W_(2)
