Hello everybody and thanks for your help.
I have connected the following circuit.
and now I want to measure the current going in several places. (for example RA0, RC0, RB5, RB4, etc)
The thing is I cant do it
Please dont tell me to search in the internet. I have. For example:
https://learn.digilentinc.com/Documents/135
so I know the theory. (I have measure current in the past I remember too)
But somehow, for example I cant measure the current so can someone teach me where should I put the connections of my multimeter?? I am using the fluke multimeter.
I for example broke the circuit going to RA0 and put the multimeter there... and nothing... 0 Amp always.
I measure the voltage, it is working fine. but always 0 Amp. and I am sure that is not true,
I cant either analyze that circuit to theoretically calculate the current. I mean maybe the one with the switch that seems simple (like in all textbooks, why textbooks only have simple examples)
Other than that my motor doesnt move with the 0.1μF capacitor, I had to take it out.
I would like to measure the current in the motor as well, but I cant even do something simple as the one in the potentiometer.
Help very much appreciated
EDIT: I have tried the simplest of circuits (in that homepage) My multimeter doesnt even measure that. Am I doing something wrong with the connections I wonder... I put the red cable in A and the black cable in COM and put the lever in A
EDIT2: I found that probably the fuses got blowed....
How can I repair that....
And if someone can teach me to calculate currents theoretically in this circuit I would be very much grateful.
