Understanding the concepts of capacitors

Click For Summary
SUMMARY

This discussion centers on the fundamental concepts of capacitors, specifically the relationship between electric potential and capacitor charging. When a capacitor is connected to a voltage source, it accumulates charge on one plate, creating a voltage difference, or electric potential, between its plates. Understanding this process is crucial for grasping how capacitors function in electrical circuits.

PREREQUISITES
  • Basic knowledge of electrical circuits
  • Understanding of voltage and current
  • Familiarity with the concept of charge in physics

I feel so frustrated because I could not understand the basics of this topic. My teacher spent like 1 week trying to explain it. I understood the math of capacitors, but I could not understand what an electric potential is. For example, what do you really mean? when you have a capacitor and apply it an electrical potential??. Here you have conceptual questions. Help me please

For example, what do you really mean? when you have a capacitor and apply it an electrical potential??.

Basically it means you are charging up the capacitor by connecting it to a voltage source. That will put electrons on one plate so that there is a matching voltage difference (electric potential) between the two plates.
