Astable Multivibrator Circuit Analysis

Thought for 7 mins 10 sec

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

Circuit	Change	Full cycle	Left LED on-time	Right LED on-time	Result
Task 1 / baseline	Two cross-coupled 10 µF Capacitors	1.72 s	0.892 s	0.892 s	Clean, nearly symmetric
Task 2	Add 100 µF Capacitor across the right LED + 470 Ω Resistor branch	2.91 s	1.39 s	1.51 s	Oscillates, but asymmetric
Task 3	Replace both 10 µF Capacitors with 1 µF Capacitors	0.462 s	0.230 s	0.230 s	Clean, nearly symmetric
Task 3 variant	One 10 µF Capacitor and one 1 µF Capacitor	0.660 s	0.165 to 0.175 s	0.485 s	Strongly 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

Make lab results table

Add duty cycle
