An electric eel delivers a current of 0.75 to a small pencil-thin prey 15 long.

Question

An electric eel delivers a current of 0.75 to a small pencil-thin prey 15 long.

1.If the eel's "bio-battery" was charged to 400 , and it was constant for 20 before dropping to zero, estimate the resistance of the fish..

2..Estimate the energy delivered to the fish.
Express your answer using two significant figures.


3.Estimate the average electric field (magnitude) in the fish's flesh.
Express your answer using two significant figures.

If anyone can help that would be grateful! I already got the question wrong, but I am stuck between the last 2 questions. How would i go about?

Explanation / Answer

(1) Resistance of wire is R = V /I                                   = 400 V / 0.75A                                   = 533.33 (2) the Power P = VI Then the energy E = P*time                             = VIt                             = 400V*0.75A*20x10-3 s                                     = 6.00 J (3) Average electric field is E = V / L                                              = 400V / 0.15 m                                         = 2666.66 N/C                                         = 2.666 kN/C
