When you were a kid, did you take stuff apart just to find out what was inside? Today's stuff is harder to see without specialized equipment, so we tear apart old analog phones to see the componentry that converts voice to electric current and back again. Then we compare this seemingly larger than life componentry of the 19TH century to today's semiconductor based versions. All things being equal, Ohm's Law is why smartphones work the same way as a candlestick phone. Furthermore, Ohm's Law is the fundamental principle of all circuit design including smartphone RF and Logic circuit designs. So, in the spirit of taking stuff apart that is meaningful, we offer telephone workshops at our museum.
