Chapter 4 Flashcards
1
Q
how to use the node voltage equation
A
Select a reference node
Assign a node voltage to each node
Write KCL equations for each node except the
reference node
Setup a matrix of equations and solve for the
unknown variables
2
Q
how to use node voltage with a dependant source
A
solve for the dependant source with terms you know
3
Q
supernode
A
is used to avoid introducing an ad-hoc
current variable in writing KCL equations when a
voltage source is connected between two nodes
neither of which is the reference node
- When two nodes are connected by a voltage source
(independent or dependent) they combine into a
supernode for writing KCL equations
4
Q
supermesh
A
- A supermesh is used to avoid introducing an ad-hoc
voltage variable in writing KVL equations when two
meshes share a current source - When two meshes share a current source (independent
or dependent) they combine into a supermesh for
writing KVL equations
