Astable multivibrator has no stable state. Alternate switching of the transistor produces square waveform in the output of this astable multivbrator

Thank you for explaining this circuit. Nicely rendered. And thank you for your "practical" presentation at the last too!

Best explanation, it should be on top search list on this topic. I've wasted multiple hours trying to understand from different videos, but none of the video explained everything like this video. Thank you for the video. Love from Nepal 🇳🇵

No brother. This theory wrong. Once capacitor charge 0.7 volt. And can not charge again 0.7. Because discharge not occur. How possible again capacitor charge ?
@vasiqshair
@vasiqshair 7 лет назад
The way you have connected RL1 and R2 makes sense. I have seen other explanations that say the capacitor is charged through RL1 which doesn't make sense because the transistor won't turn on if the negative plate of the capacitor is facing Q2. Good job.
@EEAcademy2022
@EEAcademy2022 7 лет назад
C2 charges through R2 because only that path can connect C2 with Vcc when Q2 is off. If C2 charges through RL1, there will be no direct connection between C2 and Vcc, so that cannot be the charging path
@vasiqshair
@vasiqshair 7 лет назад
Another question: C2 charges when Q1 is in ON state. When does C2 discharge?
@MahiMahi-oy9gt
@MahiMahi-oy9gt 4 года назад
C2 get discharge when Q1is in off state

@btobin86
@btobin86 5 лет назад
Awesome video! The only thing I am a little confused about is why int he very beginning, how come since one transistor is on the other is off? If both are trying to drive on at first, what makes one magically switch off? After this point though, I understand why the two switch states.
@Driftload
@Driftload 6 лет назад
It does make sense so far I think, however when C2 charges, how comes C1 is not charging simultaneously also? Is it because the voltage is Vcc at the negative terminal of the capacitor?
@MahiMahi-oy9gt
@MahiMahi-oy9gt 4 года назад
InMy Idea As ​​the Discharging path for c1is lower then that of c2 therefore c1will discharge more rapidly

@snehamurya8205
@snehamurya8205 8 лет назад
Nicely explained. But i have a doubt sir when we give Vcc in starting what is the path of current/ voltage so that one of the transistor will get 0.7 V and will get on.
@EEAcademy2022
@EEAcademy2022 8 лет назад
+Sneha Murya, may be you know similat transistors do not have identical B-E and B-C junction voltage. the transistor with lower base-emitter junction voltage should turn on first.
