Study Notes
Unit Step Function
- Also known as the Heaviside Function.
DC Steady State
- Assumes circuits have reached a stable state with constant currents and voltages.
- Components behave predictably: capacitors are open circuits, inductors are short circuits.
Calculating Inductor Current and Capacitor Voltage
- Calculate inductor current and capacitor voltage before a change in input.
Nodes and Initial Conditions
- A node represents a point in a circuit where multiple components are connected.
- Initial conditions are the values of inductor current and capacitor voltage at the instant before a change in input.
Instantaneous Change
- Signifies that a change in input occurs abruptly, with no transition time.
Inductors as Short Circuits
- Inductors behave as short circuits when they are in DC steady state, meaning they offer no resistance to current flow.
