RC Circuit without Source

When a DC source is abruptly disconnected from an RC (Resistor-Capacitor) circuit, the circuit becomes source-free. Assuming that the capacitor was fully charged before the source was removed, its initial voltage, denoted as V₀, can be considered as the initial energy that stimulates the circuit.

When a DC source is removed abruptly from an RC circuit, the circuit becomes source-free.

Assuming the fully charged capacitor's initial voltage is V₀, its initial energy, which stimulates the circuit, can be obtained.
