SUMMARY

The discussion clarifies the relationship between capacitance and electric field strength in capacitors. The equation for electric field strength (E) is derived from the formula E = QC/d, where Q represents charge, C is capacitance, and d is the distance between the capacitor plates. It emphasizes that capacitance and electric field are distinct concepts, thus negating the idea of a conversion factor between them.

PREREQUISITES
  • Understanding of capacitor fundamentals
  • Familiarity with electric field concepts
  • Knowledge of basic electrical equations
  • Ability to manipulate algebraic formulas
NEXT STEPS
  • Study the relationship between charge (Q) and capacitance (C) in capacitors
  • Learn about the derivation of electric field strength (E) in different geometries
  • Explore the implications of distance (d) on electric field strength
  • Investigate the role of dielectric materials in capacitance and electric fields
USEFUL FOR

Students and professionals in electrical engineering, physics enthusiasts, and anyone seeking to understand the principles of capacitors and electric fields.

What is the equation or conversion factor?
 
Physics news on Phys.org
The potential difference across a capacitor will be QC, where Q is the charge and
C the capacitance, and then the field strength between the plates will be QC/d, where
d is the distance between the plates

Since capacitance and electric field are two different things then "conversion factor" is not really the right term to use. It's a bit like asking what is the conversion factor between mass in micrograms and speed.
