Solution
The correct option is C 3
All electric cells have two terminals, positive and negative terminal. If two cells are connected with opposite polarities as shown, the net potential difference across them is the difference of the individual EMFs of the cells.. Hence, there is no net potential difference in the case the cells are identical. Therefore, current will not flow and the bulb will not glow.
