Partially filled capacitor
Slide a dielectric slab of thickness t between the plates and see the capacitance rise.
What to notice
The slab acts like a thinner air gap: each millimetre of dielectric counts as only 1/κ mm.
Key relation
C = ε₀A / (d − t + t/κ)
Try this
Set t = d. Compare with κε₀A/d.
What you can change
- Plate area: 50 to 500 cm²
- Plate separation d: 1 to 10 mm
- Slab thickness t: 0 to 10 mm
- Dielectric constant κ: 1 to 10
