Short Answer

An electric eel develops a potential difference between its head and tail. The eel can stun a fish or other prey by using this potential difference to drive a current pulse for . What are

(a) the energy delivered by this pulse and

(b) the total charge that flows?

(a) The energy delivered by this pulse is

(b)The total charge will be

See the step by step solution

Step by Step Solution

Part (a) Step 1: Given information

We have given,

the potential difference =

Current =

Time for pulse =

we have to find the energy generated by eel for one pulse.

Step 2: simplify

Here we can find the energy, using the power.

Since the Power generated by the eel will be,

then energy will be

Part (b) Step 1: Given information

We have given

Current =

Step 2: Simplify

We can write charge as
