EVALUATION QUESTION
1. By observation, what are the values for V1 and V2 if Va and Vb are
set to 15V? Verify your answer.
2. State the relationship between mesh current (I1, I2, I3) and branch
currents (Ia, Ib).
4. Give the step how to use nodal analysis technique and mesh
analysis technique.
Ans:
The steps in the Mesh technique are,
Identify the meshes.
Assign a current variable to each mesh, using a consistent direction
(clockwise or counterclockwise).
Write Kirchhoff's Voltage Law around each mesh.
The steps in the Nodal technique are,
CONCLUSION
On the conducted experiment to get the current and voltage values
present in the circuit and through the computation of such with the use of
the Nodal Analysis & Mesh, the experimental values that were measured
through the help of a NI Multism and the theoretical values computed
were found to be almost of the same value.Generally, nodal voltage
analysis is more appropriate when there are a larger number of current
sources around. It can be used to determine the unknown node voltages
of both planar and non-planar circuits. Nodal equations are usually formed
by applying Kirchhoffs Current Law to the nodes with unknown voltages,
whereas equations based on Kirchhoffs Voltage Law are used to form the
mesh equations. Nodal analysis is the ideal technique for analysis when all
the sources in a circuit are independent current sources.
