Cool, thanks for the lessons so far. Can't wait for March!

What is the difference between a datasheet and a schematic? Datasheet - gives information about a specific part Schematic - conveys the design of an entire circuit What is the circuit symbol for a power supply? http://www.clker.com/cliparts/5/8/5/5/11970907491735964845vermeil_IEC_Cell_Symbol.svg.med...

Haha, you got me!

Well technically I solved it right though, since I calculated Toff as 0!

That was a good learning experience nonetheless

1. What are two uses of the 555 timer? Metronome, stable timer for time critical circuit 2. How many pins does a standard LM555 timer IC have and what are the names of each pin? 8 pins in total: (details given for astable mode, which was what was shown in the tutorial) 1) Ground - Most negative pote...

Hi there, got a couple of questions for those feeling particularly helpful today: 1. Question 23 from http://www.allaboutcircuits.com/worksheets/trans1.html : Suppose you need to power a 120 volt, 600 watt heating element from a 240 volt source. You happen to have several 240V/120V step-down transfo...

Thanks again for the help!

This is what I got using AC.. seems to be -5x voltage alright:

Wait.. so it only works with AC source?

That worked for the comparator, thanks.

Will post screenshot of amplification if I ever get it working...

I experimented with what you said about Vin and Vref for the comparator, and for some reason I'm getting the completely opposite result: http://i.imgur.com/PpodZ.png Could this be a bug, or am I doing something wrong? Switching Vin to the (+) terminal and Vref to the (-) terminal also gives the comp...

I tried your adjustments and I'm still not getting 5x amplification: http://i.imgur.com/J6cWO.png This is in Multisim by the way. I'll keep fiddling with it for a bit. Thanks for your help, the site is great by the way, I was unclear on a lot of basic concepts because a lot of tutorials tend to thro...

What are two uses for Op-Amps? A: Comparator circuits and amplifier circuits. What are the two main types of amplifier configurations used with Op-Amps? A: Inverting Vo = (-R2/R1)Vi Non-inverting Vo = (1 + R2/R1)Vi How can an Op-Amp be used as a comparator? A: Connect unknown voltage to Vin (pin 3 ...
