This is an example of chemical energy being converted to electrical energy. The difference in reactivity of two metals will enable the flow of electrons through a circuit.
The potential difference created by the battery causes them to move in an electric circuit, battery is in fact a source of the "PUSH" for electrons. For more details, contact at saqibahmad81@yahoo.com
We don't normally think of electrons "flowing slowly" in a circuit. In general, electricity operates at the speed of light. It is circuit characteristics like conductivity and resistance that...
