You always manipulate your work making it difficult to understand 👎

[@ArdiSatriawan]

Then find other videos

[@lordlucas0392]

Easier way: as t=infinity the inductor behaves as short circuit branch. 10Ohm and 5 Ohm are in parallel so replace them with a resistor of 3.333333Ohm. Find the voltage between the top and bottom nodes. V=iR. So V=30. Divide the voltage by the 5Ohm resistance to find the current through the inductor to be 6 and plug it back into the formula. 6+(9-6)e^(-t/Tao)

[@ArdiSatriawan]

Yeah if you know the formula. I only use the basic formula for each component.

[@akhtaruzzaman5972]

Thanks sir...I can understand easily when you teach❤️❤️

[@ArdiSatriawan]

Great!

[@aymen2698]

its (u+v)' so we should get d/dt( e^10t + i) not d/dt( e^10t * i) ?????

[@ArdiSatriawan]

No

[@aymen2698]

@@ArdiSatriawan could explain pls

[@ArdiSatriawan]

@@aymen2698 already did in the video

[@ArdiSatriawan]

On serious note: It should be (uv)'

[@movafekanusinbintimohamedt1251]

sir y 2 days not upload any videos? 7.13 and 7.14??

[@ArdiSatriawan]

I am busy at the moment

[@weijasper9414]

Why can't say (IB-IA)*10=0 , that's mesh right?

[@ArdiSatriawan]

Maybe

[@Toki-jm2kb]

@@ArdiSatriawan What do you mean "Maybe"? please dont give us vague answer when we seriously nicely askiing

[@c.cody.3886]

Professor, when the switch is opened at time t=0, the inductor is also under dc condition (current from the current source can still reach the inductor) so why is it not treated as short circuit?

[@ArdiSatriawan]

It can't change instantaneously

[@sayedrezasadat4881]

Sir, IB is 9-IA isnt it?

[@ArdiSatriawan]

Don't know

[@sayedrezasadat4881]

I really confused can you explain it

[@ArdiSatriawan]

No
