I'm trying to wrap my head around Voltage and Current. I saw this analogy on a post from another site that seems to make sense:
For circuits I tend to mentally use a "plumbing" analogy. The voltage is like the water pressure, and the current is like the flow.
My struggle is understanding how this analogy would describe something like using a number of lemons in parallel as a battery. I have seen example people provide where a few lemons can be coaxed to produce around 3 volts of energy.
2 AA's can also be coaxed to produce roughly 3 volts of energy. Yet the current from the Lemon batteries is minuscule compared to that of the Alkaline batteries.
So in this analogy applied to those. The Lemon battery has 3v of pressure and low flow (current) and the Alkeline batteries have roughly the same 3v of pressure but considerably faster flow (current).
Is that difference in flow due to resistance in the lemon? I heard if you squish the lemon you get more current out of it. Could just the juice outside of the lemon produce similar Voltage/Current?
How could one using the same analogy above incorporate the cause of the difference in current between the two?
