What is the definition of capacitance (C)?
The constant of proportionality between charge (Q) and voltage (V):
What is the definition of a capacitor?
A device that stores electrical charge and potential energy using electric fields.
What is the definition of the Farad (F)?
The unit of capacitance, where 1 F = 1 C/V.
What is the definition of potential difference (V)?
The difference in electric potential between two points, proportional to the charge stored in a capacitor.
What is the definition of charge (Q)?
The fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. In capacitors, it refers to the amount of electrical charge stored on the plates.
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.
Compare the effect of increasing the plate area (A) versus decreasing the distance (d) on the capacitance of a parallel plate capacitor.
Increasing A: Increases capacitance proportionally. | Decreasing d: Increases capacitance inversely proportionally.
