anonymous one year ago Physics Kirchhoff's rules; finding voltage in series circuit given the electrical potential difference at battery with loads with unknown resistance. Thanks

1. anonymous

Based on the diagram below

2. anonymous

I need to calculate the voltage at Delta V given the electrical potential differences necessitated at each load station to make a circuit. I know that 60V will be the starting point but given the "unknown" resistance I am slightly void of reason

what does the statement of Kirchoff's loop rule say??

5. anonymous

I am aware that principle of resistance in series circuit assumes Rt=R1+R2+R3...

6. anonymous

Right? @ganeshie8

7. rajat97

i think that there is no need to use that equation you can do it by only using kirchoff's loop law it says that if you loop the circuit from a starting point and then come to that point again, the total potential fall or rise should be 0 Volts

8. rajat97

or mathematically, the sum of all the potential differences accross each device (resistance,battery,etc.) should be 0 did you get it now??

9. rajat97

thanks for the medal @Vocaloid

Really? Adding them all makes it all zero? However I don't see how voltage will be summed to zero given all of them have positive values.

12. anonymous

That's a simple Kingdom Come

13. anonymous

Or is it really?

14. rajat97

yes that's what i mean!

15. rajat97

i'm sorry it took too long to reply

16. anonymous

Ok @rajat97 If I've seen further it is by standing on the shoulders of giants like you

17. anonymous

XD LOL

18. rajat97

i didn't get that i mean what did you mean to say? :)

19. anonymous

Do you realize we are almost equal to or exceeding the conceptual understanding of Kirchoff right now at the time? That means technically we are more informed than our past time physicistsXD

20. anonymous

world is getting smarter ever more

21. rajat97

hahahaha but to formulate the law at that time was not an easy nut to crack:)

24. anonymous

That's you and little one is me.

25. rajat97

nice drawing

26. anonymous

27. rajat97

but i don't think we are any one of them:)

28. anonymous

Well, Newton should have said " I used the shoulders of giants as springboard"

29. anonymous

Or" by sitting on the shoulders of giants according to the picture

30. rajat97

what would Sir Einstein say??

31. anonymous

If I have seen further, it is by accrediting my absurdity.

32. anonymous

and making such absurd claims as being in compliance with scientific methodology.

33. rajat97

you are damn good at english where are you from??

34. anonymous

I mean seriously, how does he even came to use the kinematics as the spring board for his relativity theory? I understand motion is all relative and there is no such thing as moving objects without having point of reference, he related that with time and space and E=mc^2 turned out to be his product of imagination which came true I mean wtf

35. anonymous

lol I was born on the planet Earth

36. anonymous

I owe the humanity my knowledge and educationXDXD

37. rajat97

you are cool!

38. anonymous

No I am a total bore

39. anonymous

you wouldn't want me aroundXD

40. rajat97

no you never know what kind of people i may like around myself;) and thanks for the medal @ganeshie8

41. anonymous

LOL! You are one of the exceptions

42. anonymous

43. rajat97

but i hate chemistry! the subjects of exceptions well, i am known as a dumb boy do you think there can be any pros of a dumb boy??? yeah my pro can be dumbness! :p

44. rajat97

i'll be back in some time

45. anonymous

Yeah your pro is that you exist in this universe hence contributing to thermal energy present which will keep the universe from big crunch

46. anonymous

Just kidding bro everyone has pros and cos

47. anonymous

and people in general LOVE each other because they belong to the same species

48. rajat97

you are really great
