SUMMARY

A capacitor functions on a DC battery by initially allowing current to flow as it charges. During the charging process, electrons accumulate on the negative plate, while positive charge builds on the positive plate. This flow of current continues until the capacitor reaches full charge, at which point it effectively acts as an open switch, halting further current flow in the circuit. This behavior is crucial for understanding capacitor dynamics in DC circuits.

PREREQUISITES
  • Basic understanding of electrical circuits
  • Knowledge of capacitor charging and discharging principles
  • Familiarity with direct current (DC) behavior
  • Understanding of electron flow and charge accumulation
NEXT STEPS
  • Study the charging and discharging cycles of capacitors in DC circuits
  • Explore the role of capacitors in filtering applications
  • Learn about the time constant in RC circuits
  • Investigate the differences between AC and DC capacitor behavior
USEFUL FOR

Electrical engineers, electronics students, hobbyists working with DC circuits, and anyone interested in the practical applications of capacitors in electronic devices.

a capacitor does not work on dc as time varying current is required for it to function then why does it work on dc battery?
 
Physics news on Phys.org
It takes some time for the capacitor to get fully charged. During this time there is current flowing in the capacitor electrons are flowing into its negative plate and accumulate negative charge there, while electrons leave from its positive plate and accumulate positive charge there. After the end of this time capacitor is fully charged and acts as a switch and there is no more current flowing in the circuit.
