# 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's wrong with my equations?

I'm trying to get the value of v_o using mesh method as it is required. The equations I'm getting are: For the mesh on the current A I have: 2 - 2(I_a) - 3(I_a + I_b) - 2(I_a + I_c) = 0 for the mesh ...

### Node Analysis with CCVS

I'm having issues solving this problem, with the CCVS. Here is what I have so far: $$-(24 - V_1) / 250 - (60I_b) / 150 = V_1 / 50$$ Which simplifies down to: $-28.8 = 120I_b + 4.8V_1.$ But without a ...

### Mesh Analysis - 4 variables

I'm working on this problem, and got stuck. The question is asking what i0 is. For Mesh 1: -16+4(i_1-i_3 )+2(i_1-i_2 )=0 6i_1 - 2i_2 - 4i_3 = 16 For Mesh 2: 2(i_2 - i_1) + 8(i_2 - i_3) -10i_o = 0 -...

### Why does each mesh equation give different I3 value? What's the correct value and final answer?

The provided solution considers the third eqn as the correct one and proceeds with the same alone. Why is the answer achievable only thru the 3rd mesh and why not the first two? Why are they giving ...

### Equivalent resistance of a network

Determine the equivalent resistance across the terminals $a-b$. I placed a $1V$ battery across $a-b$ and then used mesh analysis on $4$ loops which resulted in using $4$ equations. But is it ...

### Is there a rule for assigning polarities to resistors or is it truly arbitrary?

Sorry if this is a silly question, I'm new to circuit analysis. I'm still rather confused about how you're supposed to assign polarities to resistors in a voltage. I've been told time and time again ...

### How many meshes are in this circuit? [closed]

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....
