Astable Multivibrator Circuit Analysis

flux

Yes - here is the updated comparison table with Task 2 filled in from the real transient simulation. For switching circuits like this, the right metric is the steady-state on-time, not startup behavior
Updated simulation comparison

Table

CircuitChangeFull cycleLeft LED on-timeRight LED on-timeResult
Task 1 / baselineTwo cross-coupled 10 µF Capacitors1.72 s0.892 s0.892 sClean, nearly symmetric
Task 2Add 100 µF Capacitor across the right LED + 470 Ω Resistor branch2.91 s1.39 s1.51 sOscillates, but asymmetric
Task 3Replace both 10 µF Capacitors with 1 µF Capacitors0.462 s0.230 s0.230 sClean, nearly symmetric
Task 3 variantOne 10 µF Capacitor and one 1 µF Capacitor0.660 s0.165 to 0.175 s0.485 sStrongly asymmetric
Task 2 takeaway
  • It does oscillate
  • The added 100 µF Capacitor makes the blink slower
  • It also makes the right LED stay on a little longer
  • So Task 2 is asymmetric but stable in simulation
If you want, I can next turn this into a submission-ready lab results table with:
  • period
  • frequency
  • duty cycle
  • visual observation
