Example 7.13: At switch 1 in Fig. 7.53 is closed, and switch 2 is closed 4 s later.
Find for Calculate i(t) t 7 0. i for and t 2 s t 5 s.
Practice Problem 7.13: Switch in Fig. 7.54 is closed at and switch is closed at
Calculate for all t. Find and

Assalamualaikum Sir Khan Nazir
Sir you have done a great work for Students. Your lectures are simlple and understood . Thanks alot for your work .

V nice sir

Sir G Your Lectures Are Awesome.....

Thanks dear. Best wishes.

Sir if there is a voltage source parallel to inductor with series resistance to voltage and parallel to short circuit current we should not short circuit that 2ohm and resistance sir in 3rd sum u discussed here after all the switch is closed

[@ElectricalEngineeringAcademy]

please mail me ur doubt at [e-mail]

[@levinsonherman6777]

thankyou sir!

[@ElectricalEngineeringAcademy]

Welcome dear. Best wishes.

[@learnwithjai1489]

Sir for 3rd pls tell the calculation by using mesh analysis also🙏🙏🙏🙏.solved by you.

[@ElectricalEngineeringAcademy]

please send email giving details on [e-mail]

[@OnMyGameplay]

At the end Why didnt we calculate t=1 and t= 3 ??? because question asks that “find i(1) and i(3)” .

[@ElectricalEngineeringAcademy]

Thanks Hakan, I missed it. But if you follow the example before, you can easily calculate. The answer should be i(1)= 1.9997 A i(3)=3.589A.

[@TheDeathknight23]

At 6:01, you said that the two resistances are in series, can you kindly explain why?

[@ElectricalEngineeringAcademy]

Please re-visit 3:15 sec. The total resistance that appears across Inductor is Rth. In this case we are looking from right to left. At 6.1 we are looking from top. I f you rotate this circuit by 90 degrees clock wise, it will become same as that of 3:15. Another way to view this is just separate the inductor, and whatever is left is Rth.

Good job sir, very good explanation, ll be waiting for more videos

@ElectricalEngineeringAcademy Yeah, I understand it now, thank you so much , could you also make video about problem 7.65 , please ? It is because I stuck in this type of questions, once I understand it, I can also solve other similar question

[@abdulhannan288]

sir how do we get to know from the statement whether we need to find step response or natural response

[@ElectricalEngineeringAcademy]

In the the source free circuit questions generally a source is already connected prior to t

[@Ching-sx2nc]

​@@ElectricalEngineeringAcademy Excuse me sir, may i ask a question . In both example 1:27 and 4:13 , With your statement, the step response refer to no source is connected before t

[@Ching-sx2nc]

No offense , Just my assumption, in example 1:27 , if I follow the graph of total response of RL circuit, the current is starts from 5A at t

[@Ching-sx2nc]

@@ElectricalEngineeringAcademySame logic by using graph, if the circuit after change of switch , the voltage or current will drop down to zero finally, it is natural response, it will makes more logical to understand using graph of rl / rc circuits
