    Resistors in Parallel

    This is an algebra issue - I have written what I thought would be the correct formula for Network C - the computer doesn't like the input method, claims that it failed to parse the equation.... It liked my other two!! Mind you, this has to be in terms of R Parallel resistance - there are two...

    When is 1 watt not 1 watt?

    All the coursework asked for was in post 1 - the highest resistance of 14Ω was achieved by series connection of the three resistors. As to how much power can the largest composite resistor dissipate without burning up: Since it converts to a series circuit there is constant current at each...

    How to setup KVL equations with element laws?

    Thank you Steve, I can already see the correct direction and I thank you for it - I passed on the idea that a node could have more than 3 inputs because I had never seen an example of such... should trusted my instinct! I will review and try again tomorrow, thanks again!

    How to setup KVL equations with element laws?

    Yes, I have read the recommended reading for this past week. Some sections I have reread 3 or 4 times! It's a slow process... not realizing certain items are important until you see them in questions!

    It's meaningless drivel, they bestowed it upon me and I Verily Impishly Pester the good forum folks. ;)

    How to setup KVL equations with element laws?

    R1=1ohm R2=2ohm R3=6ohm I=11A Currently working on this problem, one of the first steps I wanted to take was to simplify the parallel combination of r1 and r2 which yields 2/3Ω. But what becomes of the currents i1 and i2? So far, KCL -i+i2-i5=0 i1-i2-i4=0 -i3=0 KVL...

    How to setup KVL equations with element laws?

    You're awesome Steve!! Thank you. I have a notebook that I have been using to jot down questions as I watched the videos, great being able to pause a lecture to formulate a questions when something pops into your mind :) I realize that the MIT course was probably a step or two above me, but I...

    When is 1 watt not 1 watt?

    I thank you! It's a blessing to have you guys to help me from bashing my head into the concrete.... :(:mad: Algebra is good, I use some low level forms all the time, but I realize how deficient I have become in multiple variable equations and moving variables around... I need to review! Khan...

    When is 1 watt not 1 watt?

    Thanks to you both for clearing that up for me. I was able to get the correct mathematical figure of 2.66W but I am still not clear as to the why of it. I have been at it from 8:30AM-3PM and it has been a waste... I really need to revisit and get more clarity on nodes, kvl and kcl - specifically...

    When is 1 watt not 1 watt?

    You are given three resistors: two 4Ω resistors and one 6Ω resistor. What is the value in Ohms ( Ω ) of the largest-valued resistor that can be fabricated by combining these three resistors? 14 - correct What is the value in Ohms ( Ω ) of the smallest-valued resistor that can be fabricated by...

    How to setup KVL equations with element laws?

    I can tell that after week 1 I am in big trouble... Unless I can become more proficient at being able to recognize and label a network I will wash out for sure! Nodal analysis is a bit vague currently, that will be the next challenge as soon as I shore up the other deficiencies...

    How to setup KVL equations with element laws?

    In the network shown you are given that V=2.0V and that the resistors have the resistances R1=4.0Ω, R2=4.0Ω, R3=2.0Ω, and R4=2.0Ω. Element Laws: Vo=2v Vr1=4i1 Vr2=4i2 Vr3=2i3 Vr4=2i4 KVL: Vo=Vr1+Vr2 KCL: i1-i2-i3=0 I dont know if I got lucky or if my intuition is improving or if this...

    How to setup KVL equations with element laws?

    That didn't take long! page 130: That is, if f (x) is the response to some excitation x, then the system is linear if and only if f (ax1+ bx2 ) = af (x1 ) + bf (x2 ). (3.17)

    How to setup KVL equations with element laws?

    I was afraid of that... I have some history with calculus, I understand the theory of it, but I am not able to put it into practice. The summation notation and function of notation give me pause... I have used Khan Academy before and found it to be a wonderful resource. There is a link to DE...

    That is really cool Adam, a very elegant solution. Are those brass bezels for banana plugs? Did you make your request directly to LT or through a rep?

    Welcome Dan. That is quite the setup behind your photo!

    How to setup KVL equations with element laws?

    Being there is a negative value associated with both the potential and current - I believe the current is flowing from the current source across R1 and through the positive terminal of the Vsource. I am afraid... this week begins: :confused::eek: Linearity and Superposition Static...

    How to setup KVL equations with element laws?

    Thanks to both of you gents! Steve, Brilliant! :) substituting values leads to: 3A+Ir1 = (2-Ir1(4Ω))/5Ω 15+5Ir1 = 2-4Ir1 13+5Ir1=-4Ir1 13=-9Ir1 Ir1 = -1.444A thus Ir2 = +1.5556A Vr1 = -5.777 Vr2 = 7.78 I find this example really interesting despite it being a simple schematic. I have...
