Dielectric in an isolated capacitor
Insert a dielectric into a charged capacitor after disconnecting its battery.
What to notice
Inserting a dielectric reduces both voltage and stored field energy when charge is fixed.
Key relation
Q constant; V = Q/C; U = Q²/(2C)
Try this
Compare fully inserted with fully removed dielectric.
What you can change
- Fixed charge: 1 to 50 µC
- Dielectric constant: 1 to 8
- Inserted area: 0 to 100 %
