Unformatted text preview: well as the Norton current and resistance I N and R N . 3. A “black box” with 3 terminals labeled E, B and C is shown in the circuit below. Assume terminal B is magically always 0.6 V more positive than terminal E, and I d is very large compared to the current flowing into terminal B. (FYI, this black box is an NPN bipolar transistor.) (a) Find V C and V E . (easy to do) (b) Find R 1 and R 2 . Hints: “Assume terminal B is always 0.6 V more positive than terminal E, …” implies what “dynamic” resistance between terminals B and E? And why does it help that I d is relatively large?...
