    Analog vs Digital > semiconductor

    What's the difference of Analog vs Digital with respect to semiconductors with respect to construction, application and circuit itself?

    why battery cars are not popular ?

    i agree , motors that runs on 12v car battery alone are still limited and usually does not have enough power. We tried to use this on an old project... it didn't go that fast :)

    Power supply Computation help please

    @help kiprono recommended an e-book which only needs 5 pts :) Thanks anyway... that's very kind of you :) Added after 29 seconds: THANKS :D

    Power supply Computation help please

    @kiprono OOOOOOHHHHHHHHHHH V(rms) = Vrms=Vm/sqrt(2) is different from Vr(rms) = 0.308Vm (for full wave rectifier) thanks kiprono... you're really a big help! any comment on my filter and regluator computation?? I saw some Power Electronics: Converters, Applications, and Design on...

    Power supply Computation help please

    Hmmm.. I think Vrms=Vm/sqrt(2) is used for Sinusoidal AC (with positive and negative half cycle) From Boylestad & Nashesky 7th ed. appendix B Vr(rms) = (V^2(rms) - V^2 dc) ^1/2 Vr(rms) = 0.308Vm (for full wave rectifier) Vr(rms) = 0.385Vm (for halfwave rectifier)

    Power supply Computation help please

    i see, rectification efficiency must be really low then approx 50% since Vr(rms) is around half of Vdc. I will also browse rectification eff. Thanks kiprono how about my computation... anyone? did i use the right Vm = 29.17 (from rectifier output to regulator input) i'm studying by myself...

    Power supply Computation help please

    Hi guys, can someone check if i did this right? I've been trying to search for this type of power supply computation but i still haven't find any. I only used formulas i found from the internet and boylestad book... using C= 100 micro RL=200 ohm If someone has a link to a...

    Q point BJT voltage divider biased

    voltage divider bias @A.Anand Srinivasan hey i'm really really sorry for my TOO elementary questions. I only have a book and this site (not enrolled;no teachers/classmates to ask help)for my usually careless mistake related questions. I get it now, i got the previous graph and this one mixed...

    Q point BJT voltage divider biased

    q point bjt I see... so Vceq=VCC only when I am looking for Q point... since Ic= 0 Thanks :)

    Q point BJT voltage divider biased

    bjt q point @Laktronics How come Vceq = Vcc - Icq * (Re + Rc) with an emitter biased circuit yet when it comes to obtaining Q point Vceq = Vcc ? And yet with voltage divider bias is it Vceq = Vcc - Icq * (Re + Rc) ? i'm confused :( :?: Added after 5 minutes: @ A.Anand Srinivasan...

    Q point BJT voltage divider biased

    voltage divider bias bjt Will voltage divider biased circuit give me the same ICq and VCEq as with Emitter biased circuit? are ICq = Vcc/ (Rc+Re) and VCEq= VCC ?? :| Thanks in advance :)[/img]

    Diode as Clipper question

    ooohhh now i get it.... that was stupid of me.. I was thinking vi is 20 then vo became 16... i get it now.... THANKS!!!!! :D

    Diode as Clipper question

    @ a_tek7 I don't quite understand... so if VA > VK diode will conduct E.g. Vi = +16 V +16V ------kA------ +4V diode will not conduct right?? how did Vo end up with 16V ? THanks a_tek7

    Diode as Clipper question

    explain clipper diode Hello Everyone! Please help me with this simple parallel clipper to me? How come at positive cycle ( Vi > 4v) diode is active/shorted? Is it because of the 'transition'? I don't understand this transition thingy...

    help me with my current div process!

    Current Division HELP? This is a VERY elementary question ...I'm very confused with this Current div process... PLease Help me hxxp://images.elektroda.net/96_1201062710.jpg I understand the I total part for both equation. I'm a bit confused with th current division part. What is the 3 ohm...
