Q
Dielectrics are primarily used for:
1.
2.
3.
A
- Dielectrics allow two large conducting sheets to be
separated without touching each other. - They enable conducting plates to attain the highest
possible potential difference through a process called
dielectric breakdown. - A capacitor’s capacitance is larger when there is a
dielectric between its conducting plates than when
there is only vacuum.
