SUMMARY

The discussion centers on the practical application of Sinusoids and Phasors using Micro-Cap version 10.0.8 for circuit analysis. The user calculated voltages and currents for various components, including V1: 2.360∠3.68°V and V2: 1.878∠-86.32°V, and sought confirmation of these values. Issues arose when the results from Micro-Cap did not align with expected outcomes, particularly regarding the voltage across the capacitor. The conversation highlights the importance of accurate circuit setup and measurement interpretation in simulation software.

Homework Statement

Hi,

I've been trying to figure this out for a while, its really annoying because it should be straight forward but its troubling me a lot.

The exercise is a practical on Sinusoids and Phasors. We are given the circuit and have to first calculate the voltage and current for each component and then 'measure' using Micro-Cap.

The Attempt at a Solution



I calculated these to be:
V1: 2.360∠3.68°V ____ I1: 1.18∠3.68°mA
V2: 1.878∠-86.32°V __ I2: 1.18∠3.68°mA
V3: 3.030∠34.51°V ___ I3: 1.01∠34.51°mA
V4: 3.030∠34.51°V ___ I4: 0.61∠-55.18°mA

Can anyone confirm these?

Also, does anyone have any experience with micro-cap?
I am using version 10.0.8 and the results from the analysis on microcap don't make sense at all. So I have a few questions on how to set this up.

Thank you

Your calculated values appear to be fine.

I've never used MicroCap, but I assume it's a Spice engine of some form; I use LTspice when I need a simulation. In what way do the results in MicroCap not make sense? Can you be more specific?
 
In MicroCap we were supposed to draw the circuit and measure the voltages and estimate the phase angle.

I did this correctly, however for the voltage across the capacitor I calculated it to be 1.878∠-86.32°V but when I look at the graph and I calculate the voltage drop (2.64-3.049=-0.409)

I must be doing this wrong?
