Study Notes
Network Theorems
- ELE 314 course covers network theorems
- Outline includes classification of networks, superposition, Kirchhoff's laws, Thevenin, Norton, reciprocity, and homogeneity
Classification of Electrical Networks
- Classification is based on two aspects: properties of circuit elements and response to different excitations
- Active and passive networks: Active elements deliver energy; passive elements receive energy
- Unilateral and bilateral networks: Bilateral elements allow current flow in both directions; unilateral elements only allow current flow in one direction
- Lumped and distributed networks: Lumped networks have components that are physically separable; distributed networks have components distributed along the network (e.g., a transmission line)
- Linear and non-linear networks: Linear networks maintain proportionality between input and output responses; non-linear networks do not (proportional characteristics may change with change in input or output).
- Time-invariant and time-variant networks: Time-invariant networks have characteristics that do not change over time; time-variant networks have characteristics that change with time.
Superposition Theorem
- Applicable to linear, bilateral networks with multiple independent sources
- Replace all but one source at a time and find response
- Sum responses from each source to determine the total response
Kirchhoff's Laws
- Current Law (KCL): The algebraic sum of currents entering and leaving a node is zero.
- Voltage Law (KVL): The algebraic sum of voltage drops around any closed loop is zero.
