Question

what will happen if 3cells are connected to 1 bulb? what will be the brightness level?​

Answer 1

Explanation:

If 3 cells connected to 1 bulb then the brightness of bulb is increased.

Answer 2

Brightness increases if cells are connected in series

Brightness will be same if the cells are connected in parallel

Explanation:

1. Cells are in series :- If we consider that cells are connected in series with one another (with alternate polarity) then the brightness of bulb will increases, as in series connection current increases hence the brightness
2. Cells are in parallel :- If we consider that cells have same emf and connected in parallel then the brightness of bulb will remain same, as in parallel the potential drop is same hence there is no as such change in the brightness of bulb
