A quick preview of the first subtitles so you know what the video covers.
today I'm going to answer a question from a patron by the name of Joseph griscavage how'd I do and first of all a big thank you Joseph for your support you really are making this possible and the question is can you explain an a stable multivibrator I think I can do that but before I do I need to go into more detail about charging and discharging capacitors than I have in the past if you think you don't need that you might want to skip ahead to around here where I start talking about a stable multivibrators themselves or if you want to go to the Practical transistor circuit you might want to skip to those points and let's take a look at my demonstration circuit and just look at capacitor charging and discharging and take it to another level and get ready to explain an a stable multivibrator so we're going to start out with a battery and a switch let's make that a 10 volt battery this is going to go to a 1 ohm resistor and a one farad capacitor and I'm going to put another switch right here just so I can discharge that capacitor so one farad one ohm 10 volts now I'm going to close this switch and leave it closed for a few seconds just to make sure that any energy in that capacitor has been discharged and it has zero volts across it now let's open that switch and see what happens when we close the switch when that happens what does the capacitor look like at the moment that switch closes the capacitor looks like what it looks like a short circuit so what we have is energy flowing into this side of the capacitor and so electricity is Flowing there and piling up and that is pushing electricity off the other side now of course what is happening is we have electrons flowing from the negative side of the battery and they're piling up on the side of the capacitor which of course is two plates of metal the electrons can't cross that insulation but they can influence electrons on the other side and push on them and it pushes electrons off so every electron that piles up here pushes off another electron on the other side
