Cell in parallel

No, the light bulb would not glow. There is no voltage across the light bulb.

The two 6-volt cells are in fact connected end-to-end, i.e. positive terminal of one cell connected to negative terminal of the other.

Let r be the internal resistance of each cell (assume identical), the current through the cells, by Ohm's Law, is 12/2r A = 6/r A

The terminal voltage of each cell = emf - potnetial drop across internal resistance = [6 - (6/r).r] volt = 0 volt

Because the bulb is connected across the cells, it is subject to zero potential difference and thus would not glow.

Not only the bulb will not grow, but the cells may get very hot or explode. The internal resistance of the 2 cells are much much smaller than the bulb. So the cells are drawing very very large current from one another causing over heat in both cells, while the current passing thru the bulb is negligible. Not enough current to light up the bulb.

In case the 2 cells are connected in parallel with the same polarity on the terminals, the potential difference between the cells is zero. So no current flows between the cells.

i find this question in books......
sorry.

I heard this question today.Are you my classmates?Just for curiosity
