Giant electric eels can deliver a shock of 470 V with up to 1.0 A of current for a brief time. A snorkeler in salt water has a
body resistance of about 730 S2. A current of about 500 mA can cause heart fibrillation and death if it lasts too long.
What is the maximum power Pmax a giant electric eel can deliver to its prey?
Pmax =
W
If the snorkeler is struck by the eel, what current i will pass through her body?
