PHYS345 Electricity and Electronics

Example with Mixed Sources - Mesh Analysis

Textbook Circuit P3.8

Identify mesh currents and label accordingly.

Node voltage specified

Write the mesh equations.

Mesh 1:     I1 = -2
Mesh 2:     - 4 I1 + 8 I2 - 4 I4 = 12
Mesh 3:     I3 = - 12
Mesh 4:     - 2 I1 - 4 I2 + 6 I4 = 10

Solve the equations to obtain the value of the unknowns.

I1 = - 2.0 A
I2 = 1.5 A
I3 = - 1.5 A
I4 = 2.0 A

Solution:

Ix = I2 - I3 
Ix = 3.0 A
