hi,friends,
here is a typical multi vibrator.
I would start with how this circuit works:
device group R2,BG2 and R3,BG1 are not the same exactly, when power supply added, one of BG1 and BG2 is on. suppose BG1 is on, then voltage of collector of BG1will go down , and the electrolytic capacitor couples this low voltage to the base of BG2, so BG2 is off.
the white part of the Electrolytic is positive,and the black part is negative.
after BG1 is on and BG2 is off, it is said a current comes from power supply---R2--C1--collector of BG1--emittor of BG1. which raise voltage of base of BG2.
my question now is since the negative side( right) of electrolytic capacitor(C1) is rising, it may be higher than positive side(nearly 0 V). I think that is not correct.that is my question. this is the first cycle of the circuit action. maybe later will be ok?
thx for reading. help me.
