In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…
When we disconnect the 5V source seen here, it takes .047 seconds to drop to 1.85V, and five times this, or .235 seconds, to discharge. If the capacitor charged up to 5V, that process would also take .235 seconds. …
A Capacitor Discharge Calculator helps you determine how long it will take for a capacitor to discharge to a specific voltage in an RC (resistor-capacitor) circuit.
