In this short video I am showing you how to use Kirchoff's Laws to calculate currents, and thus power dissipation, for a circuit with two voltage sources.
I'm retired now, but a friend of a friends son needed to evaluate/ calculate a similar circuit. It was 40yrs ago I did this at college and knew most of the calculations, but needed a few pointers (I'm also 3 days into covid, so brain fog didn't help). Thanks for an extremely clear example and taking the time to u tube it. I've sent photographs of my workings to him, so hopefully he'll be able to work through it👍
Is it possible to obtain the currents in a situation exactly like this but with another resistor at the second loop? I reckon it wouldn't be since there'd be 4 unknowns but only 3 equations...
You can assign it any direction you choose. The arrow represents a fictitious ammeter you put in to measure the mesh current. The arrow head represents the + terminal of the ammeter and the tail its - terminal.
Hi there, I have a question about "A simple DC-circuit is fed by two batteries - with equations using Kirchovs laws". Any chance we can speak about this via zoom? I desperately need help.
it deeply unsettles me that you left out the units for most of the calculations, which leads to confusion in more complicated formulas with multiple physical quantities

Possibly the best and most straight forward explanation I have seen on how to find currents in a circuit. Great job!
I have my finals coming up and my teacher didn't give us a break down of how kirchoffs law worked. This was super helpful
So good! Thank you! Nice handwriting btw, it is so clean that I really got motivated learning.
Thank you so much!! you saved me on my college assessment!!!
Thank you, Neil!
Saved me on my summative assessment.
Very useful video, thank you very much!
Good explanation sir... Great job👏👏👏🤝🤝🤝
so helpful! thank you!
Saved me on my assignment, can't say i understand it any better though. But thanks
Thank uuu
It's too much helpful for me❤️
Thanks very much...good work.
When you have your 2 final numbers can you add them instead of multiplying to make the equations match?
How i calculate current two different direction voltage source circuit. Plz i will be waiting a solution video.
thanks..you help me a lot

Thanks. Its so helpful❤️
Very helpful thanks
Beautifully explained. You just earned a 👍
Tq so much sir .🥺
Very thanks for this video bro
Helpfull information
Thnx a bunch!!!
What if I2 also have voltage source?
Can you help me? I have this same problem but the directions are both counterclockwise. How do you do that?
I did every step right and still not getting to the end. Is there a possibility that the resistors values are off?! Help please
sooooo helpful
That is the power for I2. How do you calculate total power, by adding all three?
Thank you
how do you get the voltage drop for every resistor?
I×R
@@AA-nh5wo haha thanks I needed this 2 years ago but I'm done school.
thanks a lot
Hey, if you see this I am really in need of help. What if the two simultaneous equations can't be multiplied by no number
This is amazing thank u !!
thanks

how the current for mesh B counter clock wise?
You can assign it any direction you choose. The arrow represents a fictitious ammeter you put in to measure the mesh current. The arrow head represents the + terminal of the ammeter and the tail its - terminal.
it will take less than 2 min by nodal analysis

How abot there will be a diagonal resistor in loop 2? How to solve 😭😭😭😭
