Question

How do we connect these two identical cells of 1.5 volt each to design a 3.0 volt battery?

• A. Connect terminal A to D.
• B. Connect terminal D to B.
• C. Connect terminal B to C.
• D. Connect terminal A to C.

Answer 1

Answer: (A), (C)

The correct options are
A

Connect terminal A to D.

C

Connect terminal B to C.

For connecting two or more cells to form a more powerful battery, negative terminal of one cell is attached with positive terminal of other cell. In the given diagram A and C are positive terminals whereas B and D are negative terminals. We would therefore need to connect A to D or B to C to make the bulb shinier. This is a series connection of batteries.
