Applying mesh analysis to circuits containing current sources (dependent or independent) may appear complicated. But it is actually much easier than what we encountered in the previous section, because the presence of the current sources reduces the number of equations. Consider the following two possible cases Example: 1 Using mesh analysis, obtain the current through the 10V battery for the circuit shown in figure 1. Solution: The current source is first converted to an equivalent voltage source and the loop currents are named (Figure 2)

A Super Mesh results when two meshes have a dependent or independent current source in common. Properties of a Super Mesh i. A Super Mesh has no current of its own. ii. A Super Mesh requires the application of both KVL and KCL. Note: Mess Analysis = KVL + Ohm's Law Example: Find the mesh currents in the circuit diagram given belo Mesh Analysis using KVL (EC 4) • Most useful when we have mostly voltage sources • Mesh analysis uses KVL to establish the currents Procedure (1) Define a current loop • Set a direction for each simple closed path • Number of loops needed = number of branches - 1 = b-1 • Loop currents can overlap: often many possible combination current is equal to the mesh current . Therefore the dependent source will force volts into the system, and now mesh analysis can be performed to solve for the remaining unknowns. Both analyses are appropriate in most cases. Mesh analysis should not be used in instances where the circuit has a crossover

Consider the below example in which we find the voltage across the 12A current source using mesh analysis. In the given circuit all the sources are current sources. Step 1: In the circuit there is a possibility to change the current source to a voltage source on right hand side source with parallel resistance Current source Any voltage source can be converted(or replaced by)voltage source using ohm's law.

Similar to Nodal Analysis, Mesh Analysis for both DC and AC circuits are similar. The only difference is that in AC, we are dealing with impedances instead of just resistors. The aim of this tutorial is to make Mesh Analysis for AC circuits simpler for you. Introduction to Mesh Analysis Mesh analysis is a result analysis rules correctly. Nodal and mesh analysis are also more general than circuit reduction methods - virtually any circuit can be analyzed using nodal or mesh analysis. Since nodal and mesh analysis approaches are fairly closely related, section 3.1 introduces the basic ideas and terminology associated with both approaches The independent voltage source and current source can deliver power into a suitable load, such as a resistor. The independent voltage and current source are active elements. In many situations, we separate the sources from the circuit and refer to them as excitations to the circuit. If we do this, our circuit elements are all passive * A series RLC circuit driven by a constant current source is trivial to analyze. Since the current through each element is known, the voltage can be found in a straightforward manner. V R = i R; V L = L di dt; V C = 1 C Z i dt : * A parallel RLC circuit driven by a constant voltage source is trivial to analyze Mesh analysis employs KVL (Equation 10.1) to generate the equations that lead to the circuit currents and voltages.In mesh analysis you write equations based on voltages in the loop but solve for loop currents.Once you have the loop currents, you can go back and find any of the voltages in the loop by applying the basic voltage/current definitions given in Chapter 9

current usually arises. The direction of current flow may be assumed either clockwise or anticlockwise.

Set the terms in steps 1 and 2 equal to the total source voltage in the loop is positive! the assigned loop current flows out of its positive terminal. the sign is negative if the loop current flows into its positive terminal. EXAMPLE. Illustrates the application of this format to the mesh current analysis of a circuit shown in figure-1. Voltage sources are taken into account as usual, If their direction is the same as the mesh current, their voltage is taken to be positive, otherwise negative, in the KVL equations. Usually, for current sources, only one mesh current flows through the source, and that current has the same direction as the current of the source Find the value of i in the circuit below using mesh analysis. The first thing you should notice about this circuit is that there are two different types of sources: a dependent source (the arrow in the diamond), and an independent source (the arrow in the circle). Independent sources are independent of the circuit-so that source will always push 15 A of current into the circuit, regardless. When we consider mesh-1, the current I 1 is greater than I 2. So, current through R3 is I 1-I2. Similarly, when we consider mesh-2, the current I2 is greater than I 1. So, current through R 3 is I 2 - I1.
