    because that's what I have been told to make in class. I still don't know how to plot this graph...

    Oh I should have mentioned that this is a different question and is not linked to the circuit on page 1. I made a homemade capacitor using foil and paper and used a 1k resistor.Then I calculated the RC time constant T=RC (this is probably where i went wrong) 0.632x2v=1.264v R=1000 T=20μs...

    I am trying to plot the theoretical graph of the capacitor voltage against time for the circuit components values.I have plotted the x axis on excel,however I am struggling with plotting the y axis.I am aware that that I have to use this equation Vcap=Vs(1-e^-t/RC) Vs being 2V R=1000 and C=0.020...

    This is my report,I have also attached a rubric to give you a rough idea of what is expected. I would really appreciate it if you could check it out.

    Does anyone have some spare time to check my lab report for me? it would be appreciated. I can send you the report via message or email because it wont let me attach it on here.

    Yeah that's what i did initially I found i total but for some reason I thought it was wrong.So i did 10v/100k+47k+100k+47k because ohm's law is I=V/R so now I have I which is 1/294000A But I am stuck here.

    I am trying to calculate the quantities labelled in this schematic Vr1,Vr2,ir3 and ir4 so i have to use ohms law but combine it with the rules for series and parallel resistors. What I did so far is for the first two resistors in series I=V/R therefore 10V/100k+47 not sure if this is the...

    Does that mean I can say that the difference between the theoretical voltage gain and actual gain is 20 and would the percentage error be 50%

    The discussion section in this report requires you to write make Comments on: The validity of any assumptions made. Practical problems encountered. Mistakes made. Any areas requiring more investigation. I am just not too sure on how to do this bit

    Thank you very much I also used a logarithmic scale base 10 for the frequency on the x axis as well as the gain because I forgot to mention that to you.So i just changed that myself. and ended up with this
