Input voltage is random, not for a specific country. Use transformers for your mains voltage instead.  Also keep in mind EC displays peak voltages for AC sources. RMS voltage would be peak × .71 ... so around 100 volts here.

140Vpeak is about 99VAC. if we talk about 120VAC we are talking about the RMS voltage, the DC equivalent in heat if you apply it to a resistive load. 120VAC does cause the same heat as 120VDC then they are equal in sense of RMS definition. Clear 120VAC must be higher in peak then the DC one. Its exact √2 higher. If you have 120VAC at your outlet its peak voltage is 120*1.414V=170Vpeak.

Don't why has chose this mislesding,, word in their voltage source menu.....AMPLITUDE,,,, well what amplitude.!? Peak.!? RMS.!? Peak to peak or average or DC equivalent.!? even "I" the expert Noob got confused..

@hurz I'm aware that EC uses peak voltage instead of RMS. I just chose a random voltage and a frequency that is inbetween of what is common around the world. Of couse IRL you would use a transformer designed for your specific country's mains voltage and frequency so it doesn't really matter anyways.

@wesetaudio. . What.!? "it doesn't really matter anyway."... It does matter,, you are on air.mr.,,. Where are you!

No offence you know..!.but why put it on public. If it doesn't really matter...!? Is it a gift you don't want, !? Its not fun for us either, do why bother if it doen't really matter.....are you drunk.!? Excuseme.

@kiani's extremely hazardous "fire" circuits explode in your face and then burn your house down...don't post demeaning posts my nauseating friend...😡

@kiani lol, I'm just saying that the input voltage and the transformer turns ratios don't matter for this curcuit and thus are random. You would need to get specific transformers for your country anyways IRL. This is just a basic curcuit to show a concept, not something you would plug right into your wall.

And by the way, there ARE countries, like Japan using 100V mains ( around 140Vpeak) so the input would be correct in those places.

Now you say, we know.. The circuit description would have been the perfect place for it. You are on air.. Live show,, nobody can read junctures,,,

is ok if you do not know what the difference about peak and rms and DC and AC or whatever. I haven't told that to inform you, cuz i was guessing you know it. But here are more users reading circuits and for them i did the comment not for you. So now its exact for Japan, while the frequency and voltage was first a lazy guess... its ok.

@hurz it wasn't my intention to make it for Japan... however I was trying to say there are many voltages throughout the world. So why should I design in for a specific voltage instead of just a random one, does that make it a wrong curcuit? Not really.

@kiani yes you're probably right abou that.

Before using random values without any note to the readers its better to make it for one specific region. Normaly we see here 120VAC 60Hz or 230VAC 50Hz, japan i dont remember we havn't to many.
