The Bio-Battery - Power for the future. (So easy a 10 year old can do it.)

Step 4 Abstract- What is a Bio-Battery and how does it work?

A Bio-Battery battery consists of two different metals suspended in an acidic solution.

All batteries have 2 sides, Positive "+" and Negative "-" sides which are called terminals. Electrons flow, like water in a river, from the "-" electrode terminal, let's call it the top of a waterfall, of a battery, through a conductor, towards the "+" electrode terminal, let's call this the bottom of the waterfall, of a battery.

When electrons flow from the top of the waterfall to the bottom it is called current. It is very similar to the movement of a real river current but is so small you can't see it.

The movement of the waterfall has a moving force that pushes, this movement is called current. When this moving force (current) is measured, it is measured it what is called voltage or volts.

This moving force is going to make the LED light up.

Please remember even though this is a very low voltage High voltage can Burn or Kill!

The moving force is called Current and we measured it with Amperes... Volts is the strength of that current.

My understanding is that voltage (which is AKA EMF or electro-motive force) is the "moving force". Current is the flow of electrical charge.

OK lets say we have 1V and 200A with this source we can melt an electrode of 5mm and in reverse we have a source of 200V and 1A what we do with that? just a spark well now, what in this two sources is the one with the more force?

[Crucio]

The ability to melt an electrode is not the definition of force. In your example, you're helping show why voltage used to be called EMF. In a 1V/200A scenario, the voltage will not arc noticeably because there isn't enough "moving force" or "pressure" to jump gaps. Voltage is required to push through resistances.

Notice also that the same amount of power exists in both cases. (When I studied EE in college, we used the formula p = i e where p is power, i is current, and e is EMF (voltage).)

insomartin's water analogies describe it well, though it might be easier to think of current as the flow rate.

[insomartin]

let's assume it's water... voltage is the pressure at any given time. and Current is the amount of water in at any given time you can fill a bucket (capacitor) hour glass shaped pipe (resistor) transistor or vacuum tube or a switch (valve) fountain (antenna) a overhead tank (power supply) a sea wave could be (AC current) hydro pump/motor/tubine piston as a (solonoid)

Nice approach!

The water confuses me a little my way of thinking volts is how strong the charge is current is how much is there.

I love the water thing btw
