:s i am sorry , i'll explain
all what we saw in the study in ohm law , V= RI
electronic it is not really my specialty , i study Instrumentation pertroliere (in French) and i choosed the wrong subject to study !
we never did any simulation or build any circuits , my responsable teacher is away in another country and left me alone
all i asked is how to build parts like "transistors (BC550C & BD139) ,diodes(BAT85) , Capacitors (4,7μF/63 V ceramique and the other /25 v) " with circuit maker because i am new at this
i couldn't find them in it , and i don't want to do the simulation with just any diode or transistors
and i don't want to use another software because i can't effort buy thee license to use it
and the simulation != the degree because i need to build the circuits and write a 40 page report of what i did
so basically you are just helping me a little bit
i already wrote 20 page (theory part ) and i need to so the simulation then build the circuits by myself and finally finish my report
so please this is my last reply , if i can't get the parts here I'll go find another way
