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.

Calculate sheet resistance in finite element method

I have a simulation with several polygonial mesh cells (Voronoi-mesh) and their centers of gravity \$P_i\$, each with its own electrical potential. Every cell has the same height \$h\$ all over. How do I calculate the Resistors \$R_{12}\$ and…

What is the voltage drop across the 10 ohm resistor?

What is the voltage drop (V1) across the 10 ohm resistor? Can I use voltage division to get V1? Like V1 = (20 V x 10 Ω) / (10 Ω + 4 Ω) But when I use nodal analysis and mesh analysis I get a different answer (12.30 V). Which one should I use? Or…

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…

Find current 'i' using Nodal Analysis

Here I know how we apply nodal analysis, but can somebody explain how can we calculate the current 'i' if there is no resistor in that particular wire? I have shown my approach and working so far. I would really appreciate any guidance to steer me…

Limitations of When to Use Mesh Current Method

For this circuit, is it possible to solve for i solely with the mesh current method? I know that this would be even easier to do with application of the fundamental laws or the node voltage method; I just want to better understand the limitations…

Situation with controlled source in Mesh Analysis. Situations without solution?

I was analyzing the circuit below, and by using Mesh Analysis (this I am currently practicing), I obtained that the voltage at the \$6k\Omega\$ resistor (R6) is \$9V\$. I was able to work this out and then checked with the simulator. simulate this…

Nodal and Mesh analysis

I need to find the currents on each resistor of this circuit: Where \$\beta\$ is a constant with units of resistance. Applying Kirchhoff's laws the equations are: $$ I_1+I_3-I_2 = 0 $$ $$ V_0-I_1R_1-I_2R_2 = 0 $$ $$ \beta I_1-I_3R_3-I_2R_2 =…
