How does the collector current change in a junction transistor, if the base region has larger width?

How does electric current produce heat?

How does the junction width change when a p-n junction is forward biased?

For an n-p-n transistor in the common emitter configuration, draw a labelled circuit diagram of an arrangement for measuring the collector current as a function of colelctor emiter voltage for at least wo different vlaue sof base current. Draw the shape of the curves obtained. Define the terms outpout resistance

In a silicon transistor, a change of 7.79 mA in the emitter current produces a change of 7.7 mA in the collector current. What change in the base current is necessary to produce an equivalent change in the collector current?

In a transistor, a change of 7.9 mA in emitter current produces a change of 7.8 mA in the collector current produces a change of 7.7 mA in the collector current. What change in the base current is necessary to produce an equivalent change in the collector current?

How does the width of the depletion region of a p-n junction vary if the reverse bias applied to it decreases?
