| Description | Place two plates as close as you can without touching them. Slide them a little bit apart until you can clear see the deflecting of electroscope. Insert a dielectric between the plates, or take it away of the plates, what happened? Can you explain it? |

| Description | Compare the capacitance of the demounted capacitors which has small spacers between the two plates or a big piece of dielectric between the two plates. What is your conclusion? |
| Note | Instead of using LCR meter, you can use electrometer which can be connected to a computer monitor. |
