| Q. |
From the given circuit, using silicon BJT, what is the value of the saturation collector current? |
| A. | 5 ma |
| B. | 5.36 ma |
| C. | 5.45 ma |
| D. | 10.9 ma |
| Answer» B. 5.36 ma | |
| Explanation: to obtain an approximate answer, under saturation the bjt is on and hence acts like a short circuit. however, ideally a drop exists for the transistor which is a fixed value. for an exact answer, if the bjt is a silicon transistor, then drop vce = 0.2v and current is 12-0.2/2.2=5.36 ma. | |
