Hey all, i have a circuit that contains a diode and 2 resistors here is a link to the image http://img46.imageshack.us/img46/2562/41930604.png what i am think is that VL = 0.7V because of the silicon diode so IL = 0.7/750*10^-3 = 0.9333 mA and V0 = 0.7V but i am not sure of my answerer
i am kvsivanarayanareddy . i work in mnc company in engineering job. i completed B.Tech in electronics &communication , i want to prepare group 2 exams in ap. pls give me suggetion for preparing group, how iwill start preparation pls send to my mail .which topocis i will concertrate . how i will reach my goal pls suggest to my question.
