In this video I will used the MESH method to find the voltages across a 200ohm resistor and across the collector and the emitter of a transistor circuit.

    I just want to thank you, I spend all semester in an electronics class and just couldn't grasp the methods my teacher was describing to us to solve circuits like these, the mesh method honestly is the reason I passed the course, Thanks a bunch. I'll be watching your stuff regularly for the rest of my academic career in the Instrumentation program.

    Hi professor, I don't understand why the equation for KVL1 is (4.3-10000 IB-200 IE=0) but not (4.3-10000 IB-200 IB+200 IC=0) ?
    I got a bit confusing.

    Why is it V_ec instead of V_ce in the second part of the problem? I thought it would be +V_ce in the equation since there's a voltage rise going from E to C. The polarities aren't marked in the circuit for C and E so I assumed the + is by C since that seems to be where it is typically

    Mr. may I ask? Why we don't use formula I(B)=V(B)/R(B)=5V/10? it right or wrong to use this formula in transistor circuit? I'm pretty curious about it.please reply. thank you in advance

    isn·t that voltage Vec supposed to be Vce. pretty confused there but i understood what you did, thank you sir

    I AM A Physics teacher but from the beginning of my whole study about transistors,i never got the best way of solving these types of problems .Now i give thanks to you all

    Wow! Michael, I have watched so many of your physics videos and I can tell you hands down that you are the best physics teacher I have ever seen in my entire life. I have managed to pass my physics course with a pretty high mark of 95% thanks to your videos. I wish my professors were like you. So, I am currently taking transistor course and it is difficult to follow all the material given in the lecture, so I thought I should watch some YouTube videos to help me through and when, to my surprise, I see your videos show up in my search query, well I can't even begin to describe how happy I feel, I am so glad that you cover transistors in your videos. Michael, you are the best and your videos are pure gold( I should probably say pure Rhodium, rare and valuable at the same time)! I have shared your videos with all my friends and they all love them. Thanks so much for your hard work!

    I should have watched this 24 hours ago. I would not have failed my exam earlier.

    TAKES ME 4 MINUTES TO PUT THAT CIRCUIT ON A BREADBOARD AND USE A MULTIMETER!

    A big thank you to you Sir! Great lecture, on point. Seems like i'm gonna pass my exam now !
