Giant electric eels can deliver a voltage shock of 5.00 x 102 V and up to 1.00 A

Question

Giant electric eels can deliver a voltage shock of 5.00 x 102 V and up to 1.00 A of current for a brief time. What is the maximum power a giant electric eel can deliver to its prey during this time? Number The body of a snorkeler swimming in salt water has a resistance of about 605 . If the snorkeler is unfortunate enough to be struck by the eel, what current will flow through her body? Number A current of about 500 mA can cause heart fibrillation and death, if it lasts too long. Is the current through the swimmer in this case large enough to be dangerous? O yes O no What power does the snorkeler receive from the eel? Number

Explanation / Answer

1.

Power is given by:

P = V*i

Pmax = 5.00*10^2*1.00

Pmax = 500 W

2.

from ohm's law:

i = V/R

i = 500/605

i = 0.826 Amp

3.

Since if current current is greater than 500 mA, than it will be dangerous and in part 2 current is 826 mA, So

Yes, It will be dangerous.

4.

Power of snorkeler will be

P = V*i

P = 500*0.826

P = 413 W
