What is Loop analysis: Definition and 13 Discussions
Mesh analysis (or the mesh current method) is a method that is used to solve planar circuits for the currents (and indirectly the voltages) at any place in the electrical circuit. Planar circuits are circuits that can be drawn on a plane surface with no wires crossing each other. A more general technique, called loop analysis (with the corresponding network variables called loop currents) can be applied to any circuit, planar or not. Mesh analysis and loop analysis both make use of Kirchhoff’s voltage law to arrive at a set of equations guaranteed to be solvable if the circuit has a solution. Mesh analysis is usually easier to use when the circuit is planar, compared to loop analysis.
TL;DR Summary: How to write down the loop-impedance matrix in case of Current-Controlled Current Sources
Hi,
as in the following linear network, I would like to write down the loop-impedance matrix for it where there is a CCCS ##2i_1## source.
The starting point is the network elements...
For this one circuit, I've applied Kirchhoff's laws as following:
$$\left\{\begin{matrix}
V-6\Omega I_{6}-24V-2\Omega I_{2}=0\\
24V-6\Omega I_{6}-12V-24V=0\\
I_{2}+I_{6}=6A
\end{matrix}\right.$$
but the values I get for ##I## and ##V## aren't correct... what's wrong?

In the first condition when the switches 1 and 2 are open the capacitor 2 has charge on it. First the switch 1 closes and the charge flow of ##q_1=1 mC## is...
In C++ we have 2 types of data structures :-
1)simple data structure
so array and structure come in simple data structure group
2)compound data structure
so stack,queue,link list,tree come in compound data structure group.
In Indian board CBSE data structure linked list is not included it is...

I'm supposed to find the currents flowing through the circuit. While loop analysis is pretty easy, converting a bunch of complex numbers back and forth can get complicated fast. I'm not asking for the exact answer, but please look through the solution to verify if my working is correct. Many thanks.

The Attempt at a Solution
If we were to call the bottom right loop I1, the top loop I2, and the bottom right loop I3. I got the following:
I1 = 1mA
I2 = 6mA
I3 = 2mA
Which gives me a final answer of I0 = -1mA.
Is this correct?
