Question
To make a battery of two cells
- The positive terminal of one cell is connected to the positive terminal of the other cell
- The negative terminal of one cell is connected to the negative terminal of the other cell
- The negative terminal of one cell is connected to the positive terminal of the other cell
- None of these
Hint:
Back-to-back connection.
The correct answer is: The negative terminal of one cell is connected to the positive terminal of the other cell
Two make a battery from cells we have to connect them back-to-back, means positive of one cell with the negative of the other cell or vice versa and follow the same pattern far all the cells to be connected..
