Query: The Hydraulic Analogues of Basic Circuits: Labs for Online Learning
  Environments   In this paper we describe a couple of exercises that we developed for our
online first-year EM course. The labs that we describe are focused on basic
concepts from circuit analysis, namely Ohm's law and charging a capacitor with
a constant voltage source and a series resistor. To give students a visual
demonstration of these concepts and, simultaneously, provide a means for
students to collect their own unique dataset, hydraulic analogues of these
electric circuits were built and a series of videos were recorded.
Incidentally, the visual demonstrations may also help to alleviate some of the
commonly-held student misconceptions about basic circuits. For this reason,
even once in-person labs resume, we expect that the hydraulic analogue
demonstrations will continue to be useful.
