Benjamin Franklin created the first flat version of these, called Franklin Squares. Early experiments used high voltages, which caused corona discharges to skew results. Failures in one type can cause production of excess hydrogen, making them swell and pop. The reservoir type acts as a rectifier, smoothing AC current, and boric acid or sodium borate is usually used in the electrolytic type. The earliest ones, invented by Pieter van Musschenbroek, were called Leyden jars. Made up of two conducting plates separated by a dielectric, or non-conducting, substance, their effectiveness is measured in farads. For 10 points, name these electrical components that store charge.
