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 :)
@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...
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)
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...
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...
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...
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...
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]
@ 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
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...
Re: Current Division HELP?
laktronics.. thanks for that clear explanation... Now i get it .. Thanks again!! :D
myql... Thanks for the link... I will bookmark that site for future reference
Thanks again guys! :D

Current Division HELP?
This is a VERY elementary question ...I'm very confused with this Current div process... PLease Help me

I understand the I total part for both equation. I'm a bit confused with th current division part. What is the 3 ohm...
