Construct a capacitor by filling a paper cup with water. Whatis the analog of voltage in this case, and what is thecapacitance?
Poke a small hole on the side of the paper cup near the bottomand let the water drain. How is this similar to an RC circuit?
Decrease the R by making the hole slightly larger in diameterand re-run the demonstration. How is the rate of water flowconsistent with the new RC value?
Time how long it takes the cup to drain in each case andestimate the drainage rate (ounces or milliliters per second), makenote of it, and compare the two.
