1. KIRCHHOFF'S CIRCUIT LAW​


Explanation:

Kirchhoff's circuit laws are two equalities that deal with the current and potential difference in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell.

2. kirchhoff's voltage law ​


Answer:

Kirchhoff’s  Voltage  Law  (KVL)  is  essentially  the  law  of  conservation  of energy. If voltages across elements traversed from – to + are positive in sense, and voltages across elements that are traversed from + to – are negative in sense (or vice versa)

Step-by-step explanation:

:)


3. Kirchhoff's Circuit LawsFind i1, i2, and i3​


Solution:

We just add current iₐ and node v₁ in our solution.

The loop from 60-V source using KVL (Kirchhoff's voltage law) is:

[tex]60-1000i_{a}-5000i_{a}=0\\60-6000i_{a}=0\\\\i_{a}=\dfrac{60}{6000}=0.01\text{ A}[/tex]

The voltage v₀ at 5k-Ω resistor is

[tex]v_0=5000(0.01)=50\text{ V}[/tex]

Since

[tex]i_{a}=\boxed{i_{3}=0.01\text{ A}}[/tex]

it is because there are no other branches that contain elements (resistors) or sources.

Using KCL for the node v₁:

[tex](6\times10^{-3})(50)=i_{1}+i_{2}\\\\0.3=\dfrac{v_1}{2000}+\dfrac{v_1}{500}\\\\600=v_{1}+4v_{i}\\600=5v_{1}\\v_{1}=120\text{ V}[/tex]

So, the currents i₁ and i₂ are

[tex]i_{1}=\dfrac{120}{2000}\\\\\boxed{i_{1}=0.06\text{ A} }[/tex]

and

[tex]i_{2}=\dfrac{120}{500}\\\\\boxed{i_{2}=0.24\text{ A} }[/tex]

More Information:

==================================

copper is an example of conductor because is allows the energy to pass.

=================================

=================================

Law of Conservation of Charge is neither created nor destroyed because it can only from one system to another.

=================================

=================================

Chemical -> electrical > light is the energy transformation occurs when the flashlight is on. chemical energy is the first transform into electrical energy and the last transformation accours is the light energy.

5. Kirchhoff rule help me nonsense report


Please see the image for indication of loops.

Identify the loop A using Kirchhoff’s voltage law (KVL):

[tex] -5.0I_1+24.0-0.10I_1-20I_1-40(I_1-I_3)\\\text{}\hspace{40pt}-0.50(I_1-I_3)-48.0=0\\\Longrightarrow -5.0I_1+24.0-0.10I_1-20I_1-40I_1+40I_3\\\text{}\hspace{40pt}-0.50I_1+0.50I_3-48.0=0\\\Longrightarrow -65.6I_1+40.5I_3-24.0=0\quad\textsf{(Eq.1)}[/tex]

Identify the loop B using also KVL:

[tex] -78I_3+48.0-0.50(I_3-I_1)-40(I_3-I_1)\\\text{}\hspace{40pt}-0.20I_3-36.0-0.05I_3+6.0=0\\\Longrightarrow -78I_3+48.0-0.50I_3+0.50I_1-40I_3+40I_1\\\text{}\hspace{40pt}-0.20I_3-36.0-0.05I_3+6.0=0\\\Longrightarrow 40.5I_1-118.75I_3+18.0=0\quad\textsf{(Eq.2)}[/tex]

Do algebraic manipulation to solve for unknowns.

In terms of I₃ from Eq.1:

[tex]I_3=\dfrac{65.6I_1+24}{40.5}[/tex]

Then, plug it in to Eq.2 to solve for I₁:

[tex]\Longrightarrow 40.5I_1-118.75\left(\dfrac{65.6I_1+24}{40.5}\right)+18.0=0\\\\\Longrightarrow 40.5I_1-192.346I_1-70.370+18.0=0\\\Longrightarrow -151.846I_1-52.37=0\\\Longrightarrow -151.846I_1=52.37\\\\\Longrightarrow I_1=\dfrac{52.37}{-151.846}\\\\\Longrightarrow I_1=-0.345\;\text{A}[/tex]

Then, solve for I₃:

[tex]I_3=\dfrac{65.6(-0.345)+24}{40.5}\\\\\Longrightarrow I_3=0.034\;\text{A}[/tex]

Because,

[tex]I_3=I_1+I_2\\\Longrightarrow I_2=I_3-I_1\\\Longrightarrow I_2=0.034-(-0.345)\\\Longrightarrow I_2=0.379\;\text{A}[/tex]

Therefore the following currents are

[tex]\boxed{I_1=-0.345\;\text{A};\;I_2=0.379\;\text{A};\;I_3=0.034\;\text{A}}[/tex]


6. When computing complex circuits, why is it advisable to use Kirchhoff'sRules?​


Answer:

Kirchhoff's two rules allow for circuit analysis of increasingly complex circuits. While the algebraic steps required are still fairly involved, the process itself is straightforward. These laws are widely used in the field of electrical engineering.

Kirchhoff's laws are used to help us understand how current and voltage work within a circuit. They can also be used to analyze complex circuits that can't be reduced to one equivalent resistance using what you already know about series and parallel resistors.
