A level Capacitance Quizzes

Revising Capacitance with quizzes: Electric charge, capacitors, Electrostatics, etc.

( Simple A level Capacitance quizzes for GCE A level candidates )

Hi and welcome to this quiz where you will be tested on capacitance. Capacitance is a field in physics whereby charges at rest are being studied in a capacitor. Also, we'll talk about electrostatics in general. For this reason, below are some exciting quizzes on capacitance made available. Firstly, what is capacitance?

Capacitance is the ratio of the change in the electric charge to the corresponding change electric potential. There are two important notions of capacitance which are: self-capacitance and mutual capacitance. Any object or body that can be charged electrically expresses self-capacitance, and the concept of mutual capacitance is specifically important for understanding capacitor operations.

The capacitance is a function of the area of the plates, the distance between them, and the permittivity of the dielectric material between the capacitor's plates. Also, for most of the dielectric materials, permittivity and capacitance are independent of the potential difference and the total charge.

Q = CV

Where: Q = Quantity of charge in coulombs, C = Capacitance, V = Potential difference in volts.

The SI unit of capacitance is the farad (symbol: F). When a 1 farad capacitor is charged with 1 coulomb of electrical charge, it has a potential difference of 1 volt between its plates. The reciprocal of capacitance is called elastance.

Students, before getting into the exam hall should have a mastery of the basic concepts of capacitance in order to successfully answer questions under the topic. For quizzes on other physics topics, go to A Level Physics Quizzes.
