Sometimes we forget the impact that we have as teachers. Schools are busy places, and teachers are busy people, so it’s not surprising that sometimes we miss out on chances to stop and reflect upon the influence that we wield over the young people in our care. Often, it’s the little conversations, the easily-forgotten asides, the friendly smile or brief compliment that mean the most to young people - and while we might forget them by the time it comes to write the next report or plan the next lesson, those words can remain with a young person for a very long time, shaping their personality and their thoughts.
This man is the reason I am gonna ace my physics score this year! 👍🏻🙏🏻

1:11
Sir
U are truly very helpful to middle class boys like me
We can't afford tution but your videos just clear all the concept
In 11 th i am going to take Non medical just because of your videos because tutions are very expensive these days😃
2:21 during early times when the concept of electrons was not yet discovered people thought that electricity flows due to the flow of "positive charges" accross a circuit and so they thought that it flows from positive terminal to negative terminal. That's why it was made a convention that current flows from positive to negative terminal. But later it was found out that electricity is actually the flow of electrons but now since people have settled on the fact that current flows from positive to negative, it stayed that way and no one cared to change the convention
This is known as conventional current
So Crystal clear explanation sir.... thanks for helping lots of student out there...😊😊
I love how sometimes you are very serious and sometimes you teach with masti.
Thats called being an amazing teacher 😁😁
ALAKH SIR have one of the biggest success stories, what a journey,, from a small room, a single teacher and few supporters to the biggest online education platform, a big team and 6M+ supporters and still counting!!!!!!!
Concepts that you tell behind a particular formula is just awesome
Thank you for such an amazing ❤️ videos.
i wish i could've been your student
you are the best teacher i have seen tilll now
and the best thing about you is that you r spreading your knowledge across the whole world without taking any fees
Sir, you said that the potential differnce is due to work done by unit positive charge from one point to the other. If we take a negative charge then would the work done and potential difference be same?
In that case it would be work obtained, not work done.
38:00
Sir you explain the topics very well... I'm so grateful to you. I wish I had teachers as good as you in my school so that I could have understood it better ..then, and would have done something bigger and better now.
He exaplained oms law like nothing omg .....salute to you sir best teacher....literally the best
Sir your way of teaching is really amazing and great... Thank you Sir.

Some qualities of a good teacher include skills in communication, listening, collaboration, adaptability, empathy and patience. Other characteristics of effective teaching include an engaging classroom presence, value in real-world learning, exchange of best practices and a lifelong love of learning.
He is really a blessing for us during this pandemic situations specially for the students like us who are appearing for boards 2022💓🥺
Thank u sir
Now my doubts are clear but I want to know difference between potential and potential difference
Potential difference is the difference between the potential of two terminals. Suppose we have terminal A with potential 7V and B with 5V then the potential difference will be Across AB will be A-B=7V-5V=2V.
THE CURRENT FLOWS IN A CIRCUIT BECAUSE OF THE DIFFERENCE IN THE POTENTIAL OF THE TWO TERMINAL.
HOPE YOUR UNDERSTOOD.
