Electrogenic fish, like electric eels, have the ability to create fairly large voltages that can be used for defense or to stun their prey (see the photo). The electric eel has three organs along the length of its body that allow it to produce electricity. The organs contain special cells, called electrocytes, that can generate a voltage of 0.15 V/cell. When aligned, the cells resemble a stack of capacitors connected in series that allow a current of ions to flow through them. Eels are capable of producing a discharge at 860 V with a current of 1.0 A. (a) How much electrical power is delivered by the eel during a discharge? Use the information above. (b) How many cells would have to be aligned to produce a discharge voltage of 860 V? (c) What is the ratio of the capacitance of a single electrocyte to that of the equivalent capacitance of the entire stack of cells?
