Concept:
Under steady-state:
- When a capacitor, is present with a D.C supply, it behaves as an open circuit.
- When an inductor is present with D.C supply, it behaves as a short circuit
At t = 0+ :
Inductor replace with current source IL (0+) = IL (0-)
The inductor does NOT allow the sudden change in current”
The capacitor is replaced with the voltage source
Vc (0+) = Vc (0-)
The capacitor does NOT allow the sudden change in voltage.
Calculation:
The circuit at t = 0-
Vc (0-) = 5 V
Circuit at t = 0+
