Question

Giant electric eels can deliver a voltage shock of 500 V and up to 1.0 A of current for a brief time. For a snorkeler swimming in salt water, the resistance of her skin is negligible, so her body resistance is about 650 ohm (this can vary). A current of about 500 mA can cause heart fibrillation and death if it lasts too long. What is the maximum power a giant electric eel can delivery to its prey W If the snorkeler is unfortunate enough to be struck by the eel, what current will pass through her body A Is this large enough to be dangerous What power does the snorketer receive from the eel W

Explanation / Answer

part A)

max.power =V * I=500V* 1.0A=500W

part B)

current pass through body

I=V/R=500/650=0.77A

part C)

power=500*0.77=384.6W
