AC Circuits
Objectives: We want to be able to
- analyze ac circuits in the frequency domain by writing and solving mesh or node equations
- find the complete response of switched ac circuits
Reading: Sections 10.9 10.13 and 10.14
Lecture Notes:
- Node Voltage Analysis involves writing and solving the Node Equations, a set of simultaneous equations
whose unknowns are the node voltages. To write the node equations, we
- Identify the node voltages.
- Express the element currents and voltages as functions of the node voltages.
- Apply KCL at the nodes of the circuit.
- Mesh Current Analysis involves writing and solving the Mesh Equations, a set of simultaneous equations
whose unknowns are the mesh currents. To write the mesh equations, we
- Identify the mesh currents.
- Express the element currents and voltages as functions of the mesh currents.
- Apply KVL to the meshes of the circuit.
- Mesh and Node Equation examples for AC Circuits.
- The complete response of a switched AC Circuits.
Handouts:
- Node equations for dc and ac circuits.
- Mesh and Node Equations for ac circuits.
