## Nurali 2 years ago Question 6 Assume that in the circuit above, V0=10V, T=1ms, Rw=2Ω, Lw=1mH and RL=3Ω. What is the time constant (in milliseconds) associated with the rise of voltage vR? What is the time constant (in milliseconds) associated with the fall of voltage vR? What is the value of Vmax in Volts? What is the value of Vmin in Volts?

1. akash97

@Nurali : for part a n b) time constant=(Lw)/(Rw+Rl)

2. chaand.i

@akash97 , what about other parts ?

3. akash97

@chaand.i : i dont know.

4. jason10

go to circuit sandbox and make the circuit there take f=500hz square wave and run a transient for 5ms and get the answer!

5. akash97

@jason10 : ma data is like dat V0=5V, T=1ms, Rw=1Ω, Lw=1mH and RL=1Ω. dan plz write ma ans n formula if possible

6. brash

Hi, V0=5, T=0.1ms, RW=1, Lw=0.5mH, Rl=4, write answer pliz

7. WAK

i did it using sand box but m not getting the right answer....

8. jason10

@akash97 :got ur ans? @brash :got ur answer?

9. akash97

@jason10 : not at ol help me to take me out of dis

10. jason10

write ur values here

11. akash97

@jason10: V0=5V, T=1ms, Rw=1Ω, Lw=1mH and RL=1Ω. Tell me ans n method if possible

12. jason10

for akash97 vmax=4.384 v vmin=0.601v

13. jason10

for ezekiel or whatever that is... vmax=2.912v vmin=1.088v

14. hejå

what is eziekles rise and fall

15. akash97

@jason10 : still getting wrong

16. jason10

@akash97 :impossible man!i hav checked it1 maybe there's some typo!

17. captin_juba

@ jason10 can you write the formula plz

18. jason10

no formula, simulation!

19. jason10

@akash97 :i gave ezek the answer, his r right1

20. hejå

@jason10 can you say what the rise and fall it is for eziekels please

21. akash97

@e_zek_iel : have u got green marks on Q6 problems?

22. captin_juba

@ jason10 aha sry okay what about this specification plz Vo=5v ,T= 0.5ms , Rw=3 , Lw =1mH , Rl = 2

23. hejå

@e_zek_iel what were your answer for part 1 and 2 of question 6

24. WAK

how did u got the answer???? plz tell the method..... @e_zek_iel ?????

25. hejå

u ave to make the circuit

26. WAK

i have used sand box but m not getting the right answer... kindly tell if anyone got the right answer.... what's the trick in it coz i have used 2 checks

27. WAK

@jason10 tell me the values for Vo=10V, T=1ms, Rw= 2 ohms, Lw=1mH, Rl=3 ohms.....

28. WAK

how did u get these values????

29. WAK

@Nurali kindly tell the method and values for Vo=10V, T=0.5ms, Rw= 1 ohms, Lw=0.5mH, Rl=4 ohms.....

30. dancios

@WAK do you have values ?

31. WAK

i have solved tha question,,,,, tell me your values n i'll give u the answer

32. dancios

@WAK the same as yours

33. jason10

can u write the answer in general so that ppl can plug in their own value and check fr themselves?

34. WAK

i did it on software... just use sandbox of MITx....

35. jason10

same here and it works! i dunno y sum ppl couldn't get it?

36. dancios

Vo=10V, T=0.5ms, Rw= 1 ohms, Lw=0.5mH, Rl=4 ohms

37. PlayHard

Assume that in the circuit above, V0=5V, T=1ms, Rw=1Ω, Lw=1mH and RL=1Ω. please help vmax=4.384 - wrong vmin=0.601 - wrong

38. dancios

@WAK i do something wrong XD could you give answers :>

39. PlayHard

V0=5V, T=1ms, Rw=1Ω, Lw=1mH and RL=1Ω. 0.5 0.5 4.328 0.67 all correct

40. dancios

@e_zek_iel i have errors in 6a) and 6b) 6c) 7.942 (good one) and 6d) also error

41. dancios

halp!

42. brunofornari

@PlayHard u sure abt these answers? the Vmax is wrong for me.. 4.328 we have the same values

43. granyuyito

@dancios @wap 0.1 a, b

44. Zozi

can someone tell the last two parts for Vo=10V, T=1ms, Rw= 2 ohms, Lw=1mH, Rl=3 ohms ? The sandbox not helping (5.518 , 0.477) not green :(

45. rahulk

V0=10 T=.5, Rw=1 Lw=0.5 Rl=4 last part from sandbox is 0v, but marked wrong (Vmax 8 OK0

46. greatromeo

V0=5V, T=0.5ms, Rw=1Ω, Lw=1mH and RL=1Ω.
