Flux, Capacitance, Difference Potential, and Volt

AI Thread Summary
Flux refers to the flow of electric or magnetic field lines through a surface, while capacitance is the ability of a system to store charge per unit voltage. Difference potential, or voltage, measures the electric potential difference between two points in a circuit, indicating how much energy is available to move charges. When you see a value like "3 Volt," it signifies the potential energy difference that can drive current through a circuit. Understanding these concepts requires foundational study in electronics, and resources are available for beginners to grasp the basics.

I have a question about electricity and magnetism. My teacher went through these chapters in 3 days, and I am completely confused. Can some body please explain what exactly is flux, capacitance, difference potential, and voltage? And can you also explain to my what the number stands for when solving for each one? (Ex. 3 Volt, what does that mean?)

Thanks!

No one here will spend time and energy teaching you these BASICS of electronics. That would be called “spoon feeding the student”. First you need to study and try to grasp the concepts…they are NOT difficult or complicated. After you make your efforts, and if you have some specific doubts or questions, then definitely return here and ask them. Many experienced scientists and engineers here are ready to help you.

Google "basic electronics". Here are two sites to get you started. Keep a notebook.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.
