Batteries in Parallel

This is a video I made with my cousin showing that when you connect 2 dry cells of equal voltage of 1.5V in parallel, the light intensity of the light bulb remains the same. However, connecting a 4.5V cell and 1.5V cell in parallel with each other, the light intensity of the light bulb is decreased. Can you explain why? Because it has left me baffled...haha

since the three batteries are a higher voltage they are actually charging the single battery and when that happens the single battery drops the voltage down to 1.5 volts

ok lets use 12v 480amp/hour car batteries for this one, here is why. 12v+12v+12V connected in parallel does not increase the voltage but the amp/hour of how long that voltage can be maintained so 12v 1440amp/hours aka the 12v last longer, in series 12v+12v+12v the voltage output is tripled to 36v but only 480amp/hours, more kick but less time that it can be sustained, if you sit the two together with the same load the parallel circuit will last longer than the one in series. same with all batts

If you kept that plugged in, one of them might explode!

if you add a diode to the dry 1.5v positive and negative terminal there might be an increase in the flow of electrons

Electricity will follow the path of least resistance. When the single cell is introduced, the current will only travel through the single cell. Once the 1.5 cell is removed, the current has no choice but to follow the path through the three cells.

Because there is more watts added ( 2 bulbs) the current has to be slit between the two, thus dimming the bulbs.

Placing both water tanks with same pressure in parallel will just give you additional water volume. No change in pressure, current and, provided that same pipes are used, no resistance change as well. It's like extending the amount of water it can give.

Hydraulics can be related to Electricity when circuits are talked about.

I hope this helps.

Think of the battery as a pressurized water in a tank. The Wires are the pipes, and the Water is the current. The bulbs are your faucets.

Volts is the pressure, volume of water flowing in the pipe is the current, and the size of the pipe is the resistance.

If you parallel 2 water tanks with different pressures, the stronger water pressure "pushes" the weaker water pressure back in the tank, reducing the water pressure output to your faucets and filling the weaker pressure tank. (Con't)

This is for your student? :P
