Just wondering if anyone else out there uses compressed air as an analogy for voltage. My circumstances require me to teach electrical troubleshooting in a 5-day class, and all of my students know that hydraulic systems have pumps that provide "flow" instead of "pressure". I have always disliked the fluid analog because of this - so I use compressed air instead. Every kid has put air in a bicycles tire (hopefully), but none have typically had a hydraulics class or experience. Wondering is anyone agrees or has comments.
(BTW - Aside from the pump example failure, open valves and open switches are exactly opposite in their operation)
