<P>hello everyone I try to use help quick sheets and I wrote the following eq but I get the red line almost for all the results and I do exactly step by step im sure there is something missing here but I can not find it could you check it out and let me know what's is the problem </P>

<P>thank you for response I figured out , and I wrote it down, my question is , how this output plot change depend on R value, I mean I would like to add variable value of R from <U>0.1 to 5 ohm .</U> in attached file r is fixed but I want make a loop with 5 different value of R .</P>

<P>You will have to turn all constants which depend on R into functions of R and add R as additional argument to your existing functions.</P>
<P>I show it here for the first few expressions</P>

<P>I applied all the change you said and simplified the eq please check the plot . I made a R vector and it applied to all equation but as you see in picture it make no sense to me I need to show how I(current ) change due to different R, for that I need a 3 value plot which show G,I,R I tried 3d plot but it said value not defined could you explain how to make it<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="22.jpg" style="width: 745px;"><img src="https://sejnu66972.i.lithium.com/t5/image/serverpage/image-id/20518iAD06F566DAEE0FDE/image-size/large?v=1.0&px=999" role="button" title="22.jpg" alt="22.jpg" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="33.jpg" style="width: 790px;"><img src="https://sejnu66972.i.lithium.com/t5/image/serverpage/image-id/20519iEA6593BCA227133C/image-size/large?v=1.0&px=999" role="button" title="33.jpg" alt="33.jpg" /></span></P>Fri, 25 Oct 2019 05:38:40 GMThttps://community.ptc.com/t5/PTC-Mathcad/equation/m-p/633201#M187763kakomoji3232019-10-25T05:38:40ZRe: equation

<P>You did NOT apply all necessary changes.</P>
<P>What you show here is I's only dependent on phi, not on R.</P>
<P>From your remark I understand that you essentially need a 3-d plot. In that case follow my example of this thread: <A href="https://community.ptc.com/t5/PTC-Mathcad/equation/td-p/631776" target="_blank">https://community.ptc.com/t5/PTC-Mathcad/equation/td-p/631776</A></P>

<P>There are two remarks to be made regarding the definition of the function G(phi):</P>
<P>There is a FOR loop that uses loop variable n, but n is not used further in the function.</P>
<P>There is a number of IF statements, covering the range 0 to 2pi, but what if phi is <0 or > 2pi...? You need an OTHERWISE.</P>
