The correct answer is B as the bulb Y is in straight series and there is no change of current passing through it. And the curent gets equally divided among X and Y.

Ans 2:

Class : Class 8
b is answer

Ans 3:

Class : Class 10

Ans 4:

Class : Class 10
correct answer should be option B because there is no change in the current passing through lamp Y.

Ans 5:

Class : Class 7
I thought of B but after checking the solution I got it that it's A only, so the answer is A

I think B or C is correct. Master Answer explain this

I agree with omkar,maitri,abhid etc all who are saying option B because we can read that another bulb 'Z' is connected in "PARALLEL" and not in "SERIES" and as we know , if we connect many bulb with same battery in a parallel circuit , they will give same brightness if the one bulb was connected , but the consumption of battery will also increase.So, according to me , there will be no change in bulb y (NORMAL)ans should be : option "A"

Ans 17:

Class : Class 7
it is b only not c pls report an error

Ans 18:

Class : Class 6
Shouldn't the answer be option B, because it makes the most sense. No electricity or amps or power is taken away from bulb Y. Why is it answer A?

Ans 19:

Class : Class 9
i think it is b

Ans 20:

Class : Class 10
I agree with Abhaid Goel.

Ans 21:

Class : Class 3
yaa me 2 i think its b\

Ans 22:

Class : Class 6
I think (A) is the answer because the explanation in the solution makes complete sense but technically it could also be (B)

The scientific name of WBC is leukocyte. There are 5 types of leukocytes namely: Basophils , Eosinophil, Neutrophil, Lymphocyte. The scientific name of red blood cells is erythrocytes. Maybe there is no scientific name for platelets or it may appear that I don't know it.
