Question on: JAMB Physics - 2024
If a sheet of an insulating material is inserted between the plates of an air capacitor, the capacitance will
A
become zero
B
decrease
C
increase
D
remain unchanged
Ask EduPadi AI for a detailed answer
Correct Option: C
The capacitance of a capacitor is directly proportional to the dielectric constant of the material between its plates. An insulating material has a dielectric constant greater than 1. Therefore, when an insulating sheet is inserted between the plates of a capacitor, the capacitance increases.
