I have always been fascinated by Pokemon.
Tiding through the waves of time, now that I think about it : Pokemon did teach me a lot about physics, especially electricity.
What is Electricity ?
Electricity stems from a potential difference between two areas,
which allows for electromotive force to ensue in mobile electrons.
In biological cells, a voltage imbalance or a cell potential difference exists between the inside and outside of a a cell.
The cell achieves this by removing 3 sodium ions for every 2 potassium ions allows into the system. The removing process consumes energy ( ATP ).
The sodium ions leaving the cell
The Potassium ions entering the cell
Pikachu and Bioelectrogenesis
Where does pikachu gets it’s electrical powers ?
Its by a process known as bioelectrogenesis.
Bioelectrogenesis is the generation of electricity by living organisms
How it works is rather blunt. Remember I told you that the cells are maintained in a potential difference.
There are passageways /electrolytes that are present that allows a flow of ions through them.
the brain of the pikachu sends a signal through the nervous system to these
electrolytes, opening ions channels and reversing charge polarity,
causing an abrupt difference in electric potential.
The final effect is the generation of electric current, capable of going up to 100,000 Volts during its thunderbolt move.
Result : Opponent stupefied.
Water is better conductor than air
Most of animals that bioelectrogenic in nature are aquatic creatures ( electric eels, rays, cattlefish, etc ) . This is because water is a much better electrical conductor than air, therefore electrical signals signals can be transmitted through water.
This betters the chance for the organism to protect itself against predators. Pikachu is not aquatic because probably the writes didn’t want it be so – Poetic License ;P
Some other pokemons that were also bioelectrogenic were:
Eelektrik and the Eelektross
The one that ash has is a male pikachu. There is a female to the species as well. ( Look at the tail )
That’s pokemon physics for you folks.
Hope you enjoyed reading this post as much i did drafting it. Oh boy! There is physics just in about everything !
