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.
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 a capacitor?
A capacitor is a device that stores electrical charge and potential energy in an electric field.
What is a Farad (F)?
The Farad (F) is the unit for capacitance, where 1 F = 1 C/V.
What is a dielectric?
A dielectric is an insulating material placed between the plates of a capacitor to increase its capacitance.
Define potential difference (V) in the context of capacitors.
The potential difference (V) is the voltage between the plates of the capacitor, proportional to the charge stored.
What is the effect of increasing the plate area (A) of a parallel plate capacitor?
Increases the capacitance (C).
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 voltage (V) across a capacitor?
Increases the charge (Q) stored and the energy (U) stored.
What happens when a capacitor is connected to a battery?
The battery moves charge, creating an electric field between the plates.
What happens when charge accumulates on the plates of a capacitor?
An electric field is created between the plates, and potential energy is stored.
