Re: Physics for Electricians



Wow.
What are these demos? I have never seen them.

A demonstration of an Edison diode using a regular incandescent
light bulb with an external anode foil could be interesting.

A demonstration of heating a metal rod with one end fixed, the other
rolling on a sewing needle and a pointer flag might catch their interest.<<<<<<<<<<<<<
