S: For a conductor the resistance increases with increase in temperature due the decrease in relaxation time. E: Oh! What is relaxation time?
S: The average time interval between two successive collisions of electrons is called relaxation time. E: Why does the relaxation time decrease with an increase in temperature? S: Sir, as temperature increases, the collisions become more frequent and therefore the average time interval between collisions decreases. E: Define potential gradient of a potentiometer. S: The potential drop per unit length of the potentiometer wire is called potential gradient.
E: How does the sensitivity of a potentiometer vary with potential gradient? S: The sensitivity of the potentiometer decreases with an increase in potential gradient.
E: Can you explain why? Answer : Emitter current has magnitude upto 50 mA.
How does the collector current changes in a junction transistor of the base region has i large size ii large doping. The collector current shall decrease in both cases.
Why a common emitter transistor amplier is preferred over a common base transistor amplier? Can two p-n junction diodes placed back to back work as a p-n-p transistor? Answer : No. In this device, the base region will be quite thick and highly doped.

The base current will become equal to emitter due to neutralisation of majority carriers coming from emitter to collector. Why is the base region of a transistor made thin and lightly doped?
Answer : It is to reduce the base current and to increase both collector current and current gain. Matter waves-wave nature of particles, de-Broglie relation, Davisson-Germer experiment experimental details should be omitted; only conclusion should be explained.
