Introduction:
No table of contents entries found.
We will learn in this experiment 2 techniques :-
1- Nodal analysis
2- Mesh analysis
both of which allow us to investigate many different circuits The result
is a streamlined analysis, a more uniform level of complexity in our
equations
Objective:
1- Learn how to use these techniques correctly and when we use it.
2- Calculate the current and the voltage in each element through
nodal, mesh and superposition analysis.
3- How to deal with the circuit that contain many of current sources
and voltage sources

Background:
Nodal analysis, node-voltage analysis, or the branch current
method is a method of determining the voltage (potential difference)
between "nodes" (points where elements or branches connect) in
an electrical circuit in terms of the branch currents.
Mesh analysis (or the mesh current method) is a method that is used
to solve planar circuits for the currents (and indirectly the voltages) at
any place in the electrical circuit. Planar circuits are circuits that can be
drawn on a plane surface with no wires crossing each other. A more
general technique, called loop analysis (with the corresponding
network variables called loop currents) can be applied to any circuit,
planar or not
PROCEDURE:-
First we build this circuit on the bread board
but we design it on multisim live online circuit simulator

To build this circuit we need to (1K, 1K, 3K, 3K, 2K) resistors.
After that we connecting the resistors on the breadboard and connect
power supply to the circuit and checking if the circuit connected
correctly before starting the experiment

Conclusion:
A mesh current is a current that loops around the essential mesh.
The sign convention is to have all the mesh currents looping in a
clockwise direction
is incorrect in direction. It implies that the mesh current flow in
opposite direction
A negative mesh current implies that the mesh current we used is
incorrect in direction. It implies that the mesh current flow in opposite
direction
Negative network current indicates that the network current we used is
incorrect in direction. It means that the network current flows in the
opposite direction Negative network current indicates that the network
current we used is incorrect in direction. It means that the network
current flows in the opposite directiona given mesh circuit, the value of
the current source in that mesh
is equal to the mesh current on that mesh

Negative network current indicates that the network current we used is
incorrect in direction. It means that the network current flows in the
opposite direction
For mesh analysis, the basic law used was Kirchhoff’s Voltage Law
(KVL). For Nodal analysis, the basic law used was Kirchhoff’s Current
Law (KCL)
