Analysis Process

Question 0

First step in analyzing a circuit

Answer 0

Number each loop and letter each path in and out of a node

Question 1

Determining the direction of flow

Answer 1

Look at the power source, always out of positive end, into negative end, will either be clockwise or counterclockwise in the loop

Question 2

Use for the flow direction

Answer 2

1) Determines which paths lead current in or out of the nodes
2) Tells you which ends of a component are more positive or more negative

Question 3

What do you do when all your loops and charges are labeled on your ciciut?

Answer 3

Begin with KVL,

All the voltages at each point in the loop are equal to zero

Question 4

Basic circuit analysis proceedure

Answer 4

1) Find, known, Assumption, sketch
2) Label Loops
3) Label Nodes
4) KVL equations
5) KCL equations
6) Set voltages equal to the IR at those points
7) Use V=IR equations from above to assemble a matrix multiplication problem: [V]=[I]*[R], mindful of the dimensions of course
8) if nessisary, Rearrange with [x]^(-1) so that the unknown variable matrix is at the equals side
9) Use calculator to solve for the matrix of unknown variables
10) Use that value to complete the function for the quantity in question
11) Graph that function if nessisary
