so it's Ve = Vc - Vbe? ok... i missed that from just reading from wikipedia... i read the voltage on the load is *mostly* is constant for most of the operating current range... then again the examples from wikipedia has the load on the collector side...
collector side, then...
answering my own question again:
it just struck me, but maybe the capacitor was not charging not because of properties of currents in collector and emitter for any NPN, but because i've been thinking in terms of conventional current...
Let:
Q be a sub-circuit of an avalanching transistor...
i'll solve the specific circuit problem on my own... although, i would like an answer on the first question... when switching, is it better to go with the emitter on NPNs and the collector on PNPs?? do their electrical characteristics differ more than slightly higher currents?
i'm asking as i've been working on a design that to my understanding should've worked. i have a generic NPN restoring the supply voltage and feeding it's emitter output to a 2N2222 parallel to a charging capacitor for a delayed avalanche. somehow the avalanching only works when i swap the 2N2222...
alright, continuing the series...
another question i would like to as is on NPN BJTs, would it be better to put the load on the collector side or the emitter side?? in schematics, i almost always see it on the collector side (Ic = hfe * Ib), but the emitter side also works and when doing plain...
i need to know what is the lowest current that is reliable for cases such as:
a.) charging a capacitor
b.) when the current is being read by an instrument such as an ammeter
c.) logic signals
what i mean is that even outside normal conditions -- exposed to hot summers and cold winters, being...
are these NPN BJTs:

the same as those 2N2222 that has been around for since forever? can i trust that the reverse active and avalanche breakdown profiles are the same??
ok i actually just realized the flaw after i last posted. i thought of mentioning it, but i thought it will have you guys think that i am trolling. (i actually just checked again for additional posts from you guys)
yes, hero999 there needs to be a common ground here for this to be a universally...
i was wondering why is it, for just half duplex systems, don't we have a dedicated transceiver and a dedicated transmitter antenna.
ok, just hear me out...
assuming we are using grounded monopoles, we can have a resonator connected to a diode whose anode is connected to the transmitting...
also, why i am convinced that sometimes it might be helpful to consider "pulls" is that i see a lot of voltage supplies apparently provides negative voltages.
ok, i guess i lose here... in all cases "conventional current" and the idea of 0V grounding that comes with it abstracts all cases when it comes to passive components.
in active components as long as it is only immediately in series with a passive component, then it *should be safe*. if 2 or...
no, i was reffering to a "passive" comparator, sadly also being a very limited one.
there's very little voltage drop and current used in your "active" comparator... it's something very discrete that can be added with very little effect to the rest of the original circuitry.
mine is something...
