I am using a 1.5 V incandescent light bulb. I know that if I connect a 9V battery to it or any higher voltage, it will burn it due to the large current flowing through it (Ohm's law if V goes up then the current goes up as well assuming constant R).
Now I a have a 12 V mini hydro generator showing 7.0 V when water runs through it.
When I connect the generator directly to the light bulb, I would expect that the light bulb will burn. But it doesn't!
I know it has to do with the power output of the generator at that voltage which might not be enough to cause damage.
But looking at it from Ohm's law, that 7.0 voltage should cause a large current through the light bulb and damage it.
Any clarification would be appreciated.
Thanks
