040. Transformers: Behavior and Circuit Models 

There is this explanation of magnetism using relativity. I have tried extending it to the back emf generated by the inductor upon change of current with not much progress only leaving a hazy picture. By this, the abstraction of magnetic field will start to dissolve into dealing with electric fields. I wonder if there is anything in the literature that explains this. It would be really great to see your perspective on this.

You are the bestttt.

Sir how can I reach ur level!! 😭😩 Ur teaching is sooo great!! 😍

Is there a way to get this course syllabus?

good derivation for ideal, perfect transformers.. would be nice if derivation for general transformer model is also added

the problem in this explanation is that seems you used active and passive conventions for signs of voltages and directions of currents in a random manner

In the case at 35:20 ... when you calculate the currents a t = infintiy (Steady state voltages of output and input)... i calculate i2 being constant = 6 A and i1 increasing without bound i1(t)=10t. I see that the input is essentially DC (step function) which I have learned you cannot practically transform (Transformers are AC voltage device). Is the conclusion that i1 growing to infinity the reason or evidence of why transformers cannot be used on DC circuits. Also from inituitive perspective at infinity there is no changing magnetic flux at primary so it doesn't seem logical that you would have voltage on the output.

Hi prof. How to do Design a biasing current that is independent of power supply and temperature. The value of the output biasing current should be 25 x 10^-5 A Operating Conditions VCC: Min 2.7V, Typ 3.0V, Max 3.3V Temperature: Min -45°C, Typ 25°C, Max 125°C
