Definitions Used In Network Analysis

Question 1

What is an element

Answer 1

Ideal component of a network ( resistor, voltage, source, current source).

Question 2

Nodes

Answer 2

Point at the junction between two or more elements

Question 3

Loop

Answer 3

Any closed path that can be drawn through a network along which each node is encountered just once.

Question 4

Mesh

Answer 4

A loop but one which cannot be subdivided into smaller loops.

Question 5

Combining series resistors

Answer 5

Resistors are in series if they carry the same current.
Total voltage= V1+V2+V3, V=I(R1+R2+R3).
Total resistance Rtotl= V/I

Question 6

Combining Parallel resistors

Answer 6

Parallel if they have the same voltage.
I= V/ R1= GV
I= V/R, I= GV
Total resistance R= V/I
Conductance: Gtotal= I/V, Gtotal
Combine parallel resistors by adding their conductances.

Question 7

Combining two resistors in parallel

Answer 7

Total resistance is the product of the resistors / sum of resistors.
Rtotal= R1R2/ R1+ R2.

Question 8

Three resistors in parallel

Answer 8

Rtotal= R1R2R3/ (R1R2)+(R1R3)+(R2R3)
