    Kirchhoff Loop
AI Thread Summary
The discussion centers on solving Kirchhoff's Loop Problem to find the currents I1, I2, and I3. The user presents three equations derived from the circuit analysis and shares their calculated values for the currents. A confirmation is sought regarding the correctness of the equations and the resulting current values. The solution is affirmed, with a note on the alternative approach of using a single equation for potential by applying the current rule. The conversation highlights the effectiveness of different methods in circuit analysis.

Homework Statement


We are to find I1, I2 and I3 in the diagram.


Homework Equations


These are the three equations I got. I need to know if they're correct.
x=I1
y=I2
z=I3

12y-24+35x=0
35x+34z-18=0
x=y+z

The Attempt at a Solution


Values I got on solving:
I1=0.508
I2=0.511
I3=0.0029

(Note: r=1 ohm)

kindly tell me if this is correct! :)

Sign convention followed:

In the direction of the current=positive
Negative to positive plate=negative

The solution is correct. I almost never use the voltage/loop rule.

If you give the node at the top an unknown potential V, and the node at the bottom a potential
0, you only have to use the current rule once to get a single equation for V.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
