Using the npn transistor model of Fig. 6.5(b), consider the case of a transistor for which the base is connected to ground, the collector is connected to a 3-V dc source through a 2-kΩ resistor, and a 1-mA current source is connected to the emitter with the polarity so that current is drawn out of the emitter terminal. If β = 100 and IS = 5 × 10−15 A, find the voltages at the emitter and the collector and calculate the base current.

Can anybody me with this? ? (picture included.)

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.
