Control Panel
Higher resistance or capacitance makes charging and discharging slower.
Main Formula
Q = C x V
Q = 4.968 mC
Capacitor Charge & Discharge Visualizer
A capacitor stores energy as an electric field between two plates. The animated dots show how charge movement changes over time.
Capacitance Meaning
More capacitance lets the component store more charge at the same voltage.
C = 470 uF
Time Constant
tau = R x C
tau = 0.47 s
Stored Voltage
During charging, capacitor voltage rises gradually toward the supply.
Vc = 10.57V
Charge & Current Distribution
Charge Level
88.1%
How much of the capacitor's full charge is present right now.
Voltage Level
88.1%
How close capacitor voltage is to the source voltage.
Current Level
11.9%
Charging current starts high and falls as the capacitor fills.
What is Capacitor?
Definition
A capacitor is an electronic component that stores electrical charge. It is usually made from two metal plates separated by a dielectric material.
Main Rule
Higher capacitance stores more charge at the same voltage. Formula: Q = C x V.
Learning Insight
Capacitor blocks steady DC
After a capacitor is fully charged, ideal DC current no longer keeps flowing.
Current starts high
Charging current is strongest at the beginning, then drops as capacitor voltage rises.
Energy is stored in a field
The stored energy lives in the electric field between the two plates.
