In this paper we describe a couple of exercises that we developed for ouronline first-year EM course. The labs that we describe are focused on basicconcepts from circuit analysis, namely Ohm's law and charging a capacitor witha constant voltage source and a series resistor. To give students a visualdemonstration of these concepts and, simultaneously, provide a means forstudents to collect their own unique dataset, hydraulic analogues of theseelectric circuits were built and a series of videos were recorded.Incidentally, the visual demonstrations may also help to alleviate some of thecommonly-held student misconceptions about basic circuits. For this reason,even once in-person labs resume, we expect that the hydraulic analoguedemonstrations will continue to be useful.
