Question

Capacitors having lowest capacitance has medium of dielectric

Answer 1

Hey mate,

◆ Answer-
Low capacitance means low dielectric constant.

◆ Extra information-
- Capacitance of the material is related to dielectric constant as
C = ε0.A/d
- Therefore medium with small value of dielectric constant will have lower capacitance.
- This can be achieved by adding cavities to the material. Porous silicon oxide is supposed to be having least capacitance.

Hope this helps you..
