Questions fréquentes
What does increasing plate area do?
Larger plate area increases capacitance because it provides more surface for charge storage.
How does the dielectric material affect capacitance?
A dielectric's permittivity increases capacitance; materials like ceramic or plastic enhance charge storage compared to air.
