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?
