I have posted about this schematic before but for different reasons. Now I am trying to figure out why 1 reading is not correct.
The readings are VC and IC.
In trying to solve this myself, I read this in the education section here.
"electrons can easily flow from the p-type base to the n-type collector as long as the base-emitter junction is forward biased (meaning the base is at a higher voltage than the emitter)."
So I started taking readings to see if I could figure it out. The readings that I got were:
IB = 8.3 uamps. Yay, 1 right !
IC = 00 ???? or so small that I can't measure it.
VC = 4.2 mv ?????
Other readings are :
Supply = 9.1v
C-E = 4.2mv
B-G = .501v
C-G = 4.2mv
E-G = 0
G is ground.
BEG is base emitter collector and I think that I have them connected properly.
I still don't have a 1meg pot so I am using a 1meg resistor.
So, where and how do I start measuring so as to get VC and IC closer to what the thread predicts.
Thanks
