Mathcad

Join Team Mathcad plus guest presenter Marius Pop from AAC Clyde Space in Mathcad for Electrical Engineers! Originally aired February 12 2025, but available now on-demand.   This is the long-awaited EE flavour of our "Mathcad for ___ Engineers" series (we previously had Civil and Mechanical). Like the others, Anji gives a brief introduction on what Mathcad is and why electrical engineers use it, and then Marius showed examples with two Mathcad worksheets on classic problems that engineers may use Mathcad for; he solves these in several interesting methods. The remaining time was be used for live Q&A, moderated by yours truly.   The replay is available now at this link, as well as all presentation materials.

Mathcad prime 9.0This is quite a lot to look at, but I'm struggling with getting this graph as well as the following two to accept my values. I'm relatively new to Mathcad, so any tips would be more than appreciated.ive tried expanding my values to use less variables, but nothings seems to help this issue. 

Happy New Year! This month's challenge is based around electrical engineering, specifically an AC circuit.   Calculation Challenge An AC electrical circuit consists of the following components connected in series:• A 120 Volt 60 Hertz power source• A 50 Ohm resistor• A 0.20 Henry inductor• A 10 micro Farad capacitor   Calculate the following for this circuit:• The reactances of the inductor and capacitor• The impedance in the circuit• The current in the circuit• The power dissipated in the circuit• The phase angle of the circuit   Graphing Challenge Using an XY Plot or a Chart Component, graph the following in the same plot or chart over a minimum of 2 cycles:• The current in the circuit.• The voltage in the circuit.• The voltage drop across the resistor.• The voltage drop across the inductor.• The voltage drop across the capacitor.   You can use the values from the calculation challenge, or you can use generic values. The point is to communicate that the current, t

I am having trouble figuring out how to use LOOKUP with matrices. I am using Prime 10.0. "a" is an i x j matrix generated from numerous previous calculations."b" is also an i x j matrix, with each value being a constant in the attached file, but will also be non-constant in future calculations."c" is a 2 column matrix that is generated by reading a 2 column Excel table. What I am trying to generate an i x j "d" matrix that is calculated as follows:- if value in "a" is less than the value in "b" (same position in each matrix), then lookup the "a' value in the first column of "c" and return the value in the associated 2nd column in "c", or- if value in "a" is greater or equal to  the value in "b" return zero. If tried a couple of different methods, but either get an error with the vlookup function (see attached), or i get all the values in the i x j "c" matrix equal to the calculated results of the "a" matrix 0,0 position (although calculated correctly for the 0,0 pos

Hi guys, can anyone help explain why this doesn't work? I tried whatever I could to find out what is the problem with no success. Thanks. 

HiI tried to transfer my mathcad license to my new laptop.I requested at support, and they sent me that email with the file that i had to save on the new laptop in order to transfer it. But when I'm attaching the file in mathcad it still says that the host id is invalid.How can i fix this?

Dear experts,I have a dataset, and I need to calculate the areas of four regions within this dataset, as shown in the image.I would like to use Mathcad's integration function to perform this calculation. How can I apply the integration function to the imported dataset in Mathcad?

Hello, In Mathcad Prime 9.0.0.0 I am able to calculate the value of the program. In Mathcad Prime 10.0.1 I get the following error message: What is happening? The two attached calculation sheets are identical. When I define each step in the program seperately in Mathcad Prime 10.0.1, it does give me the right answer.Also, when I replace all the infinity symbols by say 10000, the problem still arises. Hope you can help me! Kind regards

How an I get results for partial derivate in Mathcad prime?  Where E:= V/d*k 

Please see the attached file for more information. This is related to my previous post from 11-Feb-2025. Essentially, I have several single column matrices that when augmented form a table of data. Data for one column in the large table is contained in Matrix A which has repeated values. Thus, Matrix A was filtered (my previous post) such that only unique values from Matrix A were used to populate Matrix C. The minimum values in Matrix B for a repeated Matrix A value were extracted and contained in Matrix D (again covered in my previous post).Please help to produce another matrix (Matrix "Gkeep") that contains the data in an adjacent column (i.e., another separate related matrix called Matrix G) that has the same row entry value as the row kept after filtering for unique values in A and minimum values in Matrix B. Hence, the original large table would be made by augmenting Matrices A, G & B. The summary table would be Matrices C, Gkeep & D.I plan to use this for several columns

This request is more fully explained in the attached file. The request is for a way to take two single column vectors or matrices that are effectively two columns of a table when augmented (i.e., namely matrix A and matrix B). The first matrix "A" has several rows that have repeated values. A function has been run to create a new matrix "C" that has removed the duplicate rows.Please help to write a function that will create matrix "D" such that "D" contains the minimum values from the second matrix "B" pertaining to rows that had the same value in matrix A. Thus, matrix D ensures that removal of duplicate rows from A does not lose the minimum associated values in "B". I think the details in the attached Mathcad Prime 10 file will help clarify this request.   

By Ronald Satz, Ph.D.This worksheet will:Solve a common two-circuit physics problem to determine charges and energy, keeping in mind the Reciprocal System Theory and the conventional theory  Apply to Physics, etc.  Perform using electric theory, Reciprocal System Theory, capacitance equations, energy equations, etc.      This paper compares the Reciprocal System theory of the capacitor to the conventional one. Conventional theory posits that neutral matter contains an equal number of positive and negative charges. It also states that capacitors, which are neutral overall, have positive charges on one plate and an equal number of negative charges residing on the other plate. In contrast, the Reciprocal System says that neutral matter is charge-free and that capacitors store uncharged electrons; the capacitor "charge" is actually just another form of energy. Consider an electrical circuit with two capacitors, one "charged" and one not, connected by an initia

i attached the file, its quite the problem. i did the actual movement using the acceleration on solid works. but i cant get my Mathcad graphs to match. i just cant help but feel like its due to my lack of experience in Mathcad. 

Hello!I have installed mathcad 15 on my computer, and am running the license setup. I choose " I want to aquire a license via the internet" and then " Educational-Student" along with the product key i recieved from my university. After logging in in the next step however, when the setup tries connecting to the PTC licensing server, i get a popup with error 403: Forbidden. Please help me resolve this issue, i am certain i have logged in with the correct credentials of my newly created PTC account.Best regards,Jesper

I'm not able to understand, what's causing the error when I create a range. Please review and guide, next step would be plotting with the values. Using Mathcad 10 

I filled the form to download the trial edition (mathcad express) many times, but after 10 days, I never received the link to download the install program. I had a previous version installed but I had to change computer, and the install program stops working at the page where we select the product to install. And now, I cannot download the new version.Can you help me

Hey all,I'm a mech e student using mathcad for the first time for my thermodynamics class.Been having a tricky time figuring things out, and already hit a wall. Not really sure how to figure this out, and I don't recall seeing any previous topic that helped, so any assistance would be appreciated.Attached is a screenshot of the issue.

Hi comunity, I need to calculate an Integral of data vectors like shown in the image.Outside the for loop Mathcad has no problem with convergence, but inside the loop MC returns the error message.Is there a trick here, or is this generally not possible?Greetings and many thanks in advanceMichael   

I have a student mathcad license on my other computer and wanted to move it to a new computer but can't seem to figure out how. At this point I am open to just purchasing a new student license but I also can't figure out how to do that either.

Hi all,I am plotting a phasor (magnitude @ angle) on a polar plot in MCAD 15.  I'm doing it in 15 because I want to make an animation as the phasor changes.    Here is the output: https://relayman.org/temp/e/output.mp4 The red dot you see moving around in the video is the endpoint of the phasor.  What I would like is for MCAD to leave a red dot at each location along the way - so in the end I would have a plot of the locus of those endpoints.  Something like the attached image. thanks  

Hello everyone!I’am trying to solve an optimización problem using minimize function but get an error “This variable is undefined”.What am I doing wrong?CarlosRomero

I can Install M15 on Windows 11, it does basic calculations, but will not insert controls or links to spreadsheets. No error messages are given. It ran fine on my previous laptop running Windows 10. What is missing ?
