-Would you have some sort of ideal LC circuit showing the periodic transfer of energy from the capacitor to the inductor and vice versa?2024-08-06
-Would you have a slinky that I could use to demonstrate what a toroidal coil looks like?2024-07-30
-That's the last demo request for the summer session since I have a 2-part final exam on Wed. and Th. Thank you!2024-08-06
-No demos on Tuesday 7/23 due to 2nd midterm.2024-07-22
-If available, I would also like to show the mechanical equivalent of heat with a thermocouple.2024-06-25
