Electric charge creates electric fields from "summary" of Fundamentals of Physics, Volume 1 (Chapters 1 - 20) by David Halliday,Robert Resnick,Jearl Walker
When an object possesses electric charge, it interacts with the space around it by creating an electric field. This field extends outward from the charged object and fills the surrounding space. The electric field exerts a force on any other charged object placed within it, causing the object to experience an electric force. The strength of this force depends on the magnitude of the charge creating the field and the distance between the charged objects. The concept of electric fields helps us understand how charged objects interact with each other even when they are not in direct contact. By studying the properties of electric fields, we can predict and analyze the behavior of charged particles in various situations. For example, electric fields play a crucial role in the operation of devices such as capacitors, which store electrical energy by utilizing the forces generated by the interaction of electric charges. In addition to affecting charged objects, electric fields also influence the behavior of uncharged objects. When a charged object is brought near an uncharged object, the electric field created by the charged object causes the charges within the uncharged object to rearrange. This phenomenon, known as polarization, results in the uncharged object experiencing a force due to the presence of the electric field.- The concept of electric charge creating electric fields is fundamental to our understanding of electricity and magnetism. It provides valuable insights into the nature of interactions between charged objects and helps us explain a wide range of phenomena observed in the physical world. By studying electric fields, we can explore the intricate relationships between charges and forces, leading to a deeper appreciation of the underlying principles governing the behavior of electrically charged particles.
