The voltage produced by a single nerve or muscle cell is qui

The voltage produced by a single nerve or muscle cell is quite small, but there are many species of fish that use multiple action potentials in series to produce significant voltages. The electric organs in these fish are composed of specialized disk-shaped cells called electrocytes. The cell at rest has the usual potential difference between the inside and the outside, but the net potential difference across the cell is zero. An electrocyte is connected to nerve fibers that initially trigger a depolarization in one side Electric eels live in fresh water. The torpedo ray is an electric fish that lives in salt water. The electrocytes in the ray are grouped differently than in the eel: each stack of electrocytes has fewer cells, but there are more stacks in parallel. Which of the following best explains the ray\'s electrocyte arrangement?

Solution

Part A

Salty water has lower resistivity compare to normal water so more current can Be produced at low voltage so option 1 is correct

Part 2

As the fish grow distance between electrolyte increases. Now electric field remain same. Relation between electric field and potential is

E = V/d

If distance increases then as electric field remain same so potential increases.

Option 1
