Can a Capacitor Have a Positive and Negative Plate Charge?

Click For Summary
SUMMARY

A capacitor cannot have one plate charged with +Q and the other with -K, where K≠Q, in a simple circuit connected to a single battery. The fundamental equation governing capacitors, C=Q/ΔV, indicates that both plates must have equal and opposite charges for the capacitor to function correctly. In practical applications, this imbalance in charge would lead to circuit instability and failure to store energy effectively.

PREREQUISITES
  • Understanding of capacitor fundamentals and charge storage
  • Knowledge of basic electrical circuit theory
  • Familiarity with the equation C=Q/ΔV
  • Concept of voltage difference in capacitors
NEXT STEPS
  • Research the principles of capacitor charge balance
  • Explore the effects of charge imbalance on circuit performance
  • Learn about different types of capacitors and their applications
  • Investigate advanced capacitor configurations in complex circuits
USEFUL FOR

Students studying electrical engineering, educators teaching circuit theory, and anyone interested in the practical applications of capacitors in electronic devices.

Homework Statement


Is is possible to have capacitor with one plate charge +Q and another charge -K, K≠Q.


Homework Equations


C=Q/ΔV.
Because i wouldn't know what to substitute for Q..

The Attempt at a Solution


I don't think it is possible for a capacitor connected to a single battery in a simple circuit. But is it possible ?

In a practical sense, no it's not possible.
