Electric eels and electric fish generate large potential differences that are used to stun enemies and prey. These potentials are produced by cells that each can generate 0.10 V. We can plausibly model such cells as charged capacitors.

(a) How should these cells be connected (in series or in parallel) to produce a total potential of more than 0.10 V?

(b) Using the connection in part (a), how many cells must be connected together to produce the 500-V surge of the electric eel?
