thankyou for your reply, i will try again using your ideas. The circuit i understand, but its the parralel reistor Z1 that confuses me when working out the voltage at 3 using nodal analysis. Many thanks Chris

Hi, I would be grateful of any advice on how to solve the problem below. My aim is to find the voltages at nodes 2, 3, and 4, by means nodal analysis and thus creating simultaneous equations and solving them using matricies or matrix in order to prove that these theories work. I...

does the circuit not act as a voltage divider network ? Why is the resulting graphical form a straight line? Thanks again

thanks very much, i have calculated the values and they are accurate with the graphical representation. However i have another question ? if i take the 1Mohm resistor out of the circuit what effects would it have on the exponential growth curve. The reason i ask is that without the...

inverted the resistances in the formula ? do you mean there is a mistake with the formula or you made a mistake by inverting them ?. Many thanks

the voltage / time curve was between 0 and 2 seconds, where at aorund 0.6 seconds the exponential growthy curve reached its max at 8.3 V. However like i say the actual math answer compared to the measured values are different ? could it be an error with the formula or with the tolerances of the...

thanks i have just put the values of capacitor and resistors into the formula with the relevant time and it is about .6 of a volt away from the recorded values. Would there be a specific reason for this due to circuit tolerances etc. I can't tell you how gratefull i am to you both

thanks to you both, i will have another look at it and take into account your suggestions and hopefully get yet another different answer but the right one. Thanks again

thankyou overt 26, did you have a look at the word document ? Many thanks Chris

Laplace help on a DC transient RC circuit ? PLEASE -------------------------------------------------------------------------------- I HAVE A RC CIRCUIT WHERE R1=100Kohm and R2=1Mohm and C=2.1micro farads with a Vin =10V, In order to calculate the voltage through the capacitor I...

I HAVE A RC CIRCUIT WHERE R1=100Kohm and R2=1Mohm and C=2.1micro farads with a Vin =10V, In order to calculate the voltage through the capacitor I deduce the following formula, Vc(s)=V/S {(((R2×1/Cs)/(R2+1/Cs)))/(((R2×1/Cs)/(R2+1/Cs)+R1) )} I then need to produce a laplace transform...
