Questions tagged [mesh-analysis]

For questions about mesh analysis, a circuit analysis method that is used to solve for the currents (and indirectly the voltages) at any place in a planar circuit (planar circuits are circuits that can be drawn on a plane surface without any wires crossing each other). Always use in conjunction with the "circuit-analysis" tag.

What is a mesh, and why not instead use independent loops for mesh analysis?

In the textbook "Fundamentals of Electric Circuits" by Alexander and Sadiku, 7th edition, p. 92, the definition of meshes depends on the the physical position of nodes. This doesn't make sense to me, because where you exactly you place your nodes…

How many meshes are in this circuit?

Aren't there three meshes here? The solution also says so. I denoted the three loops that I think are meshes, but the instructor said in class that there are 5 meshes. I just cannot find the other two. Edit: Are these the five meshes?

How to solve mesh-analysis problem?

This is a circuit I'm trying to solve using mesh-analysis. I thought I was solving it right but the answers tell me that I'm doing it wrong and I'm not sure why (only thing I know right now is that $i3 = 1.375A, which was the only answer I was…

Circuit with two independent sources

The problem is solved in book by using basic methods and v1 = -9 V, v2 = 2 V, v3 = -11 V, v0 = 2 V. However, when I applied mesh current method loop1 : current in loop1 say i1 such that direction in 2 ohm resistor is same in both loops I get…

Where did I go wrong? Mesh Analysis

Here is the problem: Here is my solution attempt: And here is the result from LTspice: The direction I chose for $$I_{1}$$ is not the direction I get in LTspice. Where did I go wrong? Somehow the numerical values are same but the direction is…

Mesh current formulas gives two different results for i2. Why does the first loop provide an incorrect current value?

Mesh current formulas gives two different results for i2. The formula derived from the second loop provides a current of 1A which is the correct answer. However, when I write my equation using the first loop I get a current of 5A. Why does the first…

Mesh Analysis with a Current sources and current direction

Here is the question provided below: My first question is how is the current 10 A flowing towards the voltage source???? Shouldn't it be in the opposite direction. I feel like my professor is using an opposite convention which is really irritating…
