Diference between current and voltage

Here there is no experiment. In this page you will see a simple way to understand what is voltage and what is current.

I don't have any figure to explain you so you will need a little more imagination.

Imagine a water fall. I'm sure that you now the Niagara fall (in the frontier between USA and Canada) and you know about the Victoria fall. In the water fall, the height of the fall is the voltage ( it's a metaphor) and the quantity of water is the current. That's sometimes you have the exact amount of volts but the device doesn't work. Maybe the fall is high enough but the water is dripping. Sometimes you will have enough water but the fall is short. You can take the Niagara fall: Very high, less water. You can take the Victoria fall: Less height, much water. I'm not sure that you know about the Iguaçu falls. That's why they say that voltage is a difference of potence and current is the quantity of energy. If you take a 220V shock with 1mA, you'll surely be safe (don't try it). But if take a 220V shock with 50A, you're maybe dead.

There one problem here. Send the solution by e-mail. You'll get an answer.

1) If you have two energy fonts of 6V and 2mA linked in serial, what will be the final configuration? And if they are linked in parallel?
