Electrical Capacitance and Membrane Area
Almost 200 years of scientific inquiry were necessary to understand that the electric skate produced its powerful electrical discharge by summing the membrane depolarizations of the cells in each prism in series and having all the prisms in parallel. Cavendishs’ “battery” consisted of 40 Leyden jars, the only means for storing electricity at that time, made of especially thin glass and should have been capable of holding an appreciable charge.
