Questions tagged [nodal-analysis]
A circuit analysis method in which Kirchhoff's circuit laws are used to determine the voltage between all nodes (points where circuit elements connect) and the current through all elements. Always use in conjunction with the "circuit-analysis" tag.

3x3 nodal analysis. I know v2 but I don't know how I can use v2 to find v1 and v3
I tried KCL but I don't know what to do from there. I hope someone can show me how to do it.
This is how I figured out v2 is 12 V.

Finding Thevenin voltage and resistance [closed]
I am struggling to find the Thevenin voltage and resistance across terminals A and B of the given circuit.
I got as far as writing KCL at nodes 2 and 3, which gave this:
$$v_\text{AB} = - G_2/G_1 e + ...

How to solve for \$i\$ using superposition?
Second semester college student. But I'm actually confused on how I'm supposed to do this.
I know that I need to find \$i\$ values on each voltage and current.
a. 12 V on, 3 mA and 9 mA off. (\$i1\$)...

Why does this op-amp circuit show current flowing like that?
This image shows an op-amp being powered. Is there any reason why it shows current flowing from the negative side of the bottom battery into the op-amp or why it shows current flowing from the ...

How can there be no Thévenin voltage with only a dependent voltage source? [closed]
I don't understand why the Thévenin equivalent is equal to zero in this case because, if the load is a resistance, then yes, the circuit would be dead as there would be no voltage drop across Vx. But ...

Exponential stability of a general \$RLC\$ circuit with sinusoidal input
I conjecture that any \$RLC\$ circuit with \$n \ge 0\$ independent sinusoidal voltage sources of the same frequency is exponentially stable.
How to prove this or if this is not true, how to modify the ...

How to derive an ODE for a general n-th order LTI circuit?
I have seen in multiple books the following fact:
Suppose we have an n-th order \$RLC\$ LTI circuit with and independent volatage source \$x(t)\$. Then a voltage \$y(t)\$ of some node in the circuit ...

Including resistance between supernodes
Here,as per the circuit,we can take \$V_1\$ and \$V_3\$ with the voltage source across them as a supernode(as the area marked in red). In the red marked portion i.e supernode,we see that current can ...
