What is the effect of increasing the distance (d) between the plates of a parallel plate capacitor?
Decreases the capacitance (C).
What is the effect of increasing the plate area (A) of a parallel plate capacitor?
Increases the capacitance (C).
What happens to the energy stored in a capacitor if the voltage across it is doubled?
The energy stored is quadrupled (since ).
What happens when a capacitor is connected to a battery?
Charge accumulates on the plates, creating an electric field and storing energy.
What happens to capacitance when a dielectric material is inserted between the plates of a capacitor?
Capacitance increases.
What is the definition of Capacitance (C)?
Capacitance (C) is the constant of proportionality between the charge (Q) stored on a capacitor and the potential difference (V) between its plates:
What is the definition of a capacitor?
A capacitor is a device that stores electrical charge and potential energy in an electric field.
What is the definition of the Farad (F)?
The Farad (F) is the unit of capacitance, defined as 1 F = 1 C/V.
What is the definition of potential difference (V)?
The potential difference (V) is the difference in electric potential between two points, which is proportional to the charge stored on a capacitor.
What is the definition of charge (Q)?
Charge (Q) is the electrical charge stored on the plates of a capacitor.
In a parallel plate capacitor diagram, what do the plates represent?
The plates represent conductive surfaces that accumulate charge.
In a parallel plate capacitor diagram, what does the distance 'd' represent?
The distance 'd' represents the separation between the two conductive plates.
