Thank you so much! This is an amazing explanation. I did have one question though. Did you use Kirchhoff's loop rule or Faraday's to get the RL circuit equation? I was watching other lectures as well, but some of them are saying that they did the closed loop integral of E dotted with dL across each part of the RL circuit, and since there is no electric field across an inductor, there is no potential drop, but the total voltage must equal -L(dI/dt).

Professor, so the time at the end above small e is simply E divided by L, correct or no.

Sir, what is happening in the circuit in this case? I mean, which events happening in this circuit while current is increasing? We can know the current-time graph is what you drew on board with solving diff. eq., but it is a real system and laws of Physics is valid here. and some events happens and due to this events current-time graph become like this. How can we explain why this circuits acts like so? What is happening there? please tell me the real physical reasons of being of the current-time graph like so...

Why is the time constant L/R as opposed to LR like an resistor-capacitor circuit?
@MichelvanBiezen
@MichelvanBiezen 6 жыл бұрын
Since an inductor opposes a CHANGE in the current, a smaller resistor will result in a final larger current and thus a larger change. Placing a smaller R in the denominator will cause a larger current change and a larger time constant.

Thanks fr the video.A concern with me is;why is l/R a function of time.i'll appreciate your response
@MichelvanBiezen
@MichelvanBiezen 5 жыл бұрын
The current is not a constant. The current start at 0 when the circuit is open. After the circuit has been closed for a while the current is V/R. The inductor prevents the current from changing instantaneously. Thus there is a gradual change of the current.

@@MichelvanBiezen when we are solving for current as a function of time we take (L/R) as a function of time in order to get integrating factor

That is not the purpose of this video. (see the other videos we have on indductors). This video explains how the current changes over time after the switch closes.
