QUESTION:

Problem 27PE

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 horizontally along the body and each containing 5000 electroplaques. Each electroplaque has an emf of 0.15 V and internal resistance of 0.25 Ω . If the water surrounding the fish has resistance of 800 Ω , how much current can the eel produce in water from near its head to near its tail?
