Electric fish generate current with biological cells called electroplaques, which are physiological emf devices. the electroplaques in the south american eel are arranged in 140 rows, each row stretching longitudinally along the body and each containing 5000 electroplaques. each electroplaque has an emf of 0.15 v and internal resistance of 0.25 ω. think of this eel as a single large battery consisting of a parallel combination of 140 sub-batteries, each made up of a series combination of 5000 cells, which are the electroplaques. the battery’s terminals are near the eel’s head and tail?
