I can't figure out why some circuits become forward biased sometimes. I
would draw you a schematic but the last time I tried it didnt' work. if you
have a circuit with two resistors in series with the gate of an SCR in the
middle of the resistors, how do you tell weather the SCR is going to be
forward biased or not? I can't figure it out for the life of me. lets say
the gate is -3.5 volts, the cathode is -9volts and the anode is 0. is it
forward biased or not. the gate is positive with respect to the cathode,
yet negative with respect to the anode. this may seem simple at first
glance but I assure you I have tried to learn electronics several times and
each time I get frustrated and give up so what the hell am I doing wrong?!
some one give me some peace!
