How do electric eels generate voltage?
― The electric eels - a type of knifefish - are capable of generating powerful electric shocks of up to around 600 volts. They use it for both hunting and self-defense. ∙ Image: Wikipedia ∙ The source of their power is a battery-like array of cells known as electrocytes, which make up around 80% of the eel's metre-long body. These disc-shaped electricity producing cells each acquire a small potential difference of around 1/10th of a volt by controlling the flow of sodium and [...].
