CSU Physics Wireless Charging of Electrical Vehicles Discussion
Let?s take a break from all of the ?book learning? and explore the world around you. For these assignments, your writing will be focused on Everyday Physics which will help you connect your Readings to things that have happened in the world around you. In this module, you will look for an article or news story/video that relates to one or more of the following topics:Gauss’ LawElectric fields to one of a variety of charge configurationsThese are pretty broad topics, but a few ideas should spring readily to mind.Provide a substantive reply to at least two of your classmates? posts:CapacitorsHow Capacitors WorCapacitors are essential components in electronic circuits that store electrical energy. They have the “capacity” to store and release electrons, similar to a battery. The relationship between capacitors and Gauss’s law lies in understanding the electric field distribution within capacitors.According to the textbook, Guass? law relates the electric field at points on a (closed) Gaussian surface to the net charge enclosed by that surface. In the case of a capacitor, when it is connected to a battery, electrons accumulate on one plate of the capacitor, creating a negative charge. Simultaneously, the other plate loses electrons, resulting in a positive charge. This charge distribution creates an electric field between the plates, which is perpendicular to the surface of the plates.The electric field between the plates of a capacitor is uniform, and its strength is directly related to the charge stored on the plates. Gauss’s law helps in understanding and calculating the electric field distribution within the capacitor. By analyzing the charge distribution and the electric field, engineers can design capacitors with specific capacitance values and voltage ratings for various applications.The article mentioned different types of capacitors used in various electronic devices. For instance, ceramic capacitors are used in high-frequency applications such as antennas, X-ray machines, and MRI machines, while supercapacitors are employed to power electric and hybrid cars. Understanding the behavior of capacitors and their charge storage capacity is crucial in choosing the appropriate type for a specific application.In everyday life, capacitors are widely used in numerous devices and systems. They are found in electronic devices like computers, smartphones, and televisions. Capacitors play a crucial role in power supply units, voltage regulation, noise filtering, and signal coupling. Additionally, they are used in flash photography, where a capacitor rapidly releases its stored energy to produce a bright flash of light.Overall, capacitors are vital components in modern electronics, and their behavior is intricately connected to Gauss’s law. Understanding the electric field distribution and charge storage within capacitors allows engineers to design efficient and reliable electronic systems that we use in our everyday lives.Hello everyone,Lightning RodAs my link says I will be discussing the electric field around lightning rods. Lightning rods are made to protect buildings from lightning strikes as lightning can easily harm people. Lightning is usually attracted to objects of higher elevation, like trees as seen in sample problem 23.4.1 where a tree is struck by lightning because the water created a path of least resistance to the tree. However, lightning rods work by providing a path of least resistance for the electrical discharge. Gauss’s law can be applied to our understanding of the electric field that surrounds the lightning rod. Designs for lightning rods are very similar to that of figure 23.21 in the textbook. Gauss’s law states that the electric flux through any closed surface is proportional to the net charge enclosed by that surface. With this understanding we can deduce that when a thundercloud carries an excess of negative charge, it induces a positive charge on the ground or nearby objects which leads to an intense electric field between the clouds and any objects. The pointed shape of the lightning rod helps concentrating the electric field lines within its vicinity. Because of said pointed shape the lightning rod is stronger than any surrounding object. The electric field strength being high around the tip of the lightning rod enhances the chances of a lightning strike being attracted to said rod than the structure being protected by the lightning rod. By providing a preferred path for the lightning discharge, the lightning rod helps to protect the structure by directing the electric current safely to the ground, preventing damage to the building’s electrical systems, minimizing the risk of fire or structural damage, and finally reducing the potential harm to people inside the structure.
