### Dielectrics in Capacitors

\[M | t+ | ★★★\]   
Parallel plate capacitor and capacitance meter with insertable dielectrics.  
\[[In-Depth Description](/presentations/dielectrics-capacitors)\]

### Temperature Dependance of Permittivity

\[S/M | t+ | —\]  
Liquid dielectrics in parallel plate capacitor are heated to demonstrate temperature effects.

### Thermoelectric Effect

\[S/M | t+ | —\]  
Thermocouple junction produces EMF with enough current compliance to energize an electromagnet.

### Skin Depth

\[M | t | ★★\]  
KISS (108 MHz) electromagnetic waves penetrate aluminum box while HDH (680 KHz) waves don't.

### Exploding Capacitor

\[M | t+ | —\]  
Electrolytic capacitor connected with reversed polarity to a far too large voltage source.
