When a battery is connected in the same order, it will cause a short circuit. On the other hand, Connecting it in the reverse order will brighten it up. The answer is b.

Ans 17:

Ishitadas from Adamas World school , Ichapur

Ans 19:

sankalp from Gyan Bharti School, Saket, Delhi
Class : Class 10
For all those who say that the figure is not there, the question refers to the figure in the previous question, that is, Q.9.A is the correct option because by in the same order it means the same order in which the cells of the battery are connected, that is, positive terminal should be connected to the negative terminal, through the wires.I, therefore, believe that option A is the correct option.If you did not understand the above explanation, then imagine that the two probes are just at the side of the battery. Now imagine that another battery is between the two probes in the same order like the other battery. Now can you imagine the circuit complete and understand why option A is correct?Hope that this comment is helpful.

For the people who didn't see the figure, the figure is the same as the one in the previous question. However, even I don't understand how the answer is (a). It should be (b)

Ayan Mandal from ADAVPS, Blgt
Class : Class 10

Ans 26:

SOUVAGYA SAHA from De Nobili School, DHANBAD
Class : Class 10
the figure is the same as in question 9........but the ans is not option A because if we add a battery between the probes in the same order , then as overall , the negative terminal of the two batteries will come in contact and as we know both the batteries will push electricity against each other and we have to subtract its voltage , thus resulting in decrease in the amount of electricity or short circuit may happen.
