“12th Class Physics Chapter 12 Quiz: Electrostatics” deal with the study of stationary electric charges and the force exerted between them. MDCAT students need to understand electrostatics, as this topic forms the very basis for many later topics related to electromagnetism and other areas within physics. In this chapter, some important topics such as charge, Coulomb’s Law, electric field, and potential are discussed. Our MDCAT Quiz on this chapter helps you in the understanding and application of these concepts during an exam.
Overview of Electrostatics
Electrostatics is the branch of physics that deals with the behavior of electric charges at rest. Starting from the basics of electric charge and its conservation, the chapter then explains that like charges repel each other while opposite charges attract. Coulomb’s Law is stated as the basic law giving the force between two point charges. The students are shown how this law can be extended to other configurations of charges and how to find the electrostatic force between the charges.
Electric Field and Electric Potential
The chapter continues with the electric field. The space surrounding a charged object where it exerts a force on other charges is called an electric field. Students will be able to calculate the strength and direction of the electric field produced by a point charge. The topic further elaborates on electric field lines and relates electric field to electric potential—how the potential energy is related to the position of a charge in an electric field. It also explains equipotential surfaces, which are surfaces of constant potential.
Capacitance
This section introduces the capacitor, an electrical device used for storing electrical energy. The chapter explains the concept of capacitance, what factors affect it, and how to find the capacitance of various configurations. It considers the parallel-plate capacitor and how the dielectric material can be used to increase capacitance. Students will learn about energy stored in capacitors and some practical applications of capacitors in electronic devices.
