If a sheet of an insulating material is inserted between the plates of an air capacitor, the capacitance will
- become zero
- decrease
-
increase
- remain unchanged
The correct answer is: C
Explanation
If a sheet of an insulating material (dielectric) is inserted between the plates of an air capacitor, the capacitance will increase.
When a dielectric material is inserted: The permittivity \(\epsilon\) increases (since the permittivity of the dielectric is greater than that of air),
This results in an increase in capacitance.
