I swear I owe you a kidney for this one. You have singlehandedly saved me at least three days worth of mindsplitting trial and error. Earned a sub for sure.
Saw from another comment and I just noticed that the video isn't wrong, also I think he never said 2.25. Anyways, the video's right because there's still an I2 on the other side which is just 1. So 1 + 2.25 = 3.25. Though this is years ago, just wanted to share haha.
Thank you so much for your videos, been watching all the circuit ones and they are so helpful (I feel confident enough to complete them now with your help!)
For anyone confused about how to find out if the currents need any kind of prefix after calculating, look at the final step of the first substitution 3.25*I2 = 10 Check your resistances in V = IR format here, V = 3.25*I2 so the R is 3.25 and whatever the mentioned prefix is (in this case kiloohms) You can multiply by that prefix to make the answer more clear: 10 = 3250*I2 which gives 10/3250 = about 0.003077A (amps) then you can convert back to a more convenient prefix 3.077mA (milliamps) Alternatively (and likely more easily), you can constantly keep track of your prefixes by writing them through every step of solving Example: writing 3.25kΩ*I2 instead of just 3.25*I2. This way you shouldn't forget what scale your answer should be on
Amazing video like always. I had been struggling with my homework and thanks to your video, I was able to finish it on time. This topic was very confusing for me, but after watching this video, I can now say I have a much better understanding on this topic.
im confused. i have similar question for my physics class but we just need to find the potential at a specific point . for example in this problem, how can i find the potential at point c
I got i1 as 0.38 mA and i2 3.08 mA as well but when i added them to find i3 and i got 3.46 for i3?? I made i1 and i2 to go the junction and i3 to leave the junction, does this make my answer wrong?
If you chose different directions, how would you know if the current is positive or negative? I chose a different direction and got a negative answer for I2, and it took me over an hour to redo it, because i thought it was completely wrong, until I did it your way and realized I just had the sign wrong!! what a waste of time, please tell me so I dont make the same mistake!
In 11 minutes you were able to cover more than my teacher did in 3 days...thanks so much!
I agree!!!!!!! I understand it soooo much better now. I will be using his videos the rest of the semester.
loooool you finished me
😮 ehh please how did the man get magnitude ?
😢@@indiaclo
You're one of the best tutor alive. Thank you so much.
Finally a video that actually went through each step properly, thank you!!!
I swear I owe you a kidney for this one. You have singlehandedly saved me at least three days worth of mindsplitting trial and error. Earned a sub for sure.
Absolutely perfect. Couldn't have explained it any better, THANKS A LOT!
Thank you sooo much for the videos , you have really helped me out for the exams . May God continue t bless you sir
Thank you from the bottom of my heart. You are a savior.
Thanks for this video! I couldn't completely understand the topic until I saw and listened your explanation
When adding the two equations 5 -1.5 i2 + 5 - 0.75 i2 = i2 how did the 1.5 and 0.75 become 3.25 I'm getting 2.25 have I missed a step? Many Thanks
Same thing 😢
I think he got a mistake but it's fine I mean.. we all do make it sometimes but, yours is just the right answer.
There is I2 on the right side and -2.25*I2 on the left side. Maybe you forgot I2 on the right side😂
Not really he made a mistake
This workout question literally was in my physics final exam yesterday what I'm regretting now is that I didn't watch it :(
at 9:01 you did 10\3.25 . You said 2.25 at first. so instead of 3.08 its 4.44.
Saw from another comment and I just noticed that the video isn't wrong, also I think he never said 2.25.
Anyways, the video's right because there's still an I2 on the other side which is just 1. So 1 + 2.25 = 3.25.
Though this is years ago, just wanted to share haha.

For anyone confused about how to find out if the currents need any kind of prefix after calculating, look at the final step of the first substitution
3.25*I2 = 10
Check your resistances in V = IR format
here, V = 3.25*I2 so the R is 3.25 and whatever the mentioned prefix is (in this case kiloohms)
You can multiply by that prefix to make the answer more clear:
10 = 3250*I2
which gives 10/3250 = about 0.003077A (amps)
then you can convert back to a more convenient prefix
3.077mA (milliamps)
Alternatively (and likely more easily), you can constantly keep track of your prefixes by writing them through every step of solving
Example: writing 3.25kΩ*I2 instead of just 3.25*I2.
This way you shouldn't forget what scale your answer should be on
Hello teacher I’m from Cambodia Thanks for sharing this Video teacher 😘🥰
Hello from Buffalo, New York!
After watching many videos....I understood it finally
Thank you so much sir!!
You're welcome!
I owe it to you man. My professor sucked at explaining this
where did u calculated current in each resistor?
Not me watching than before my exam 🎉
Thank you so much 😍 ... your class is very helpful for me ... Now I can solve this math ... 😊😊😍😍
I2 value is 4.4444
The best 11 min before i go to exam xD thanks a lot. Take love
Thank you, this was explained well. you give a perfect amount of time for me to follow along and work out the problem with you.
Very good approach.. i went through many lectures on kirchhoff's law problems.. they were all incomplete
absolutely perfect teaching
Thank you so much i struggled with a similar problem for weeks! this really helps!!
Brilliant, well done! Thanks so much.
For part a how did u get 3.25?? Skipped a step and I've been over it many times where does the extra 1 come from?
There is I2 on the right side and -2.25*I2 on the left side. Maybe you forgot I2 on the right side.
(-2.25)I2+10=I2
=> 10=I2+(2.25)I2=(3.25)I2
Your video realy helps me.....thank you so much!!!
This made so much sense. thank you very much!
Very useful. You earned a new sub
Very nice presentation.
Amazing video like always. I had been struggling with my homework and thanks to your video, I was able to finish it on time. This topic was very confusing for me, but after watching this video, I can now say I have a much better understanding on this topic.
why did you change the direction of loop 2,
it should be 2.25 not 3.35
yea he didnt notice but still a great help tho..
Loop1) I1=5.0mA-1.50*I2,
Loop2) I3=5.0mA-0.75*I2,
I2=I1+I3=(5.0mA-1.50*I2)+(5.0mA-0.75*I2)=10mA-2.25*I2
I2=10mA-2.25*I2, ∴3.25*I2=10mA, I2=10mA/3.25
@@꺄호-u4t how do u get 3.25???
@@faheem1216 Check the equation in the last row. There is I2 on the left side and -2.25*I2 on the right side. Maybe you forgot I2 on the left side.🙂
Please I don't understood how you got the magnitude after the potential difference?
OMG you're awesome i've learn so much in 11min
Can you finding the power delivered to each resistor in this problem?
im also confused where did 3.25 came from?
There is I2 on the right side and -2.25*I2 on the left side. Maybe you forgot I2 on the right side.
(-2.25)I2+10=I2
=> 10=I2+(2.25)I2=(3.25)I2
This clears up a lot of issues that I had. Thanks!
How do you find total current after finding I1, I2, and I3?
im confused. i have similar question for my physics class but we just need to find the potential at a specific point .
for example in this problem, how can i find the potential at point c
Shut up
Multiply current and resistance
do you always have to move in a different loop the 2nd time?
i think even the like is not enough to thank you ❤️❤️❤️
Sir when I add what you got on I1 to 13, it didn't match the answer you got on I2
how about if there is only one battery and three resistors and I need the current of each branch of the circuit? pleasee answerrr
Absolutely fantastic! Thank you!
Thank you very much
you have very good explaining method
I got i1 as 0.38 mA and i2 3.08 mA as well but when i added them to find i3 and i got 3.46 for i3?? I made i1 and i2 to go the junction and i3 to leave the junction, does this make my answer wrong?
I made a mistake here for i1 I got negative 0.38 so I forgot to use it
And indeed I got 2.7 for i3😢🎉🎉🎉🎉🎉 let's go!!!
Amazing❤❤❤❤
I like your voltage value. ;)
i loved the video and how you taught but that yellow light is killing my eyes
Thank you, but matrices to solve it is overkill, I’d use that rather than going the long way.
Thankyou, such a good example question and walkthrough!
You are the best thank yoh is very easy to understand the lecture
So, you are using conventional current flow
Please can you make a video of 3 loops with multiple voltage switches
How to determine which current for each resistance??
Thank You! 👍
hey i have a circuit problem like this can i get some help?
THE ANSWER IS WRONG, YOU MADE A MISTAKE IN YOUR CALCULATIONS,
He made a huge mistake. This was a classic node voltage analysis problem that could have been done in 3 minutes. (b) was positive 69.23
u r de best thanks a lot
Nice explanation
thank you man. from colombia.
If only potential difference at f what is the answer
I2 is 4.44 since 0.75 and 1.25 is 2.25 not 3.25
1.5*
(1)I2 + (0.75)I2 + (1.5)I2 = 3.25 I2. you're forgetting to add the 1 that already exists on the right side of the equation.
It's 2.25 when you add
The true goat
Moo . . .
If you chose different directions, how would you know if the current is positive or negative? I chose a different direction and got a negative answer for I2, and it took me over an hour to redo it, because i thought it was completely wrong, until I did it your way and realized I just had the sign wrong!! what a waste of time, please tell me so I dont make the same mistake!
MoniSmiles you did it right. Your negative sign was just indicating that your current is actually going in the opposite direction.
Have seen you’ve written your answer is wrong sir on 3.25 instead of 2.25
Bless you. I finally understand this.
I wish the background wasn’t yellow😢
nice
this is so helpful thank you thank you thank youuu
thank you!!!
Thank you - you are the best!!!
oh god atlast now i understand kirchhoff law
God bless you sir!
THANK YOU SOOO MUCH
I think Its 2.25 not 3.25
yes yes
you're a life saver
you're a light saber*
Thank you sooooo much

Thank you so much
can we take I2=I1+I3..
Yup
thank you so much....
Lol I wish you were my teacher!!!

i2 answer is wrong
I2 is not wrong.
(-2.25)I2+10=I2
=> 10=I2+(2.25)I2=(3.25)I2
=> I2=10/3.25 Yessss
Thank you so much
