|
a) |
Low cost |
b) |
Low dissipation energy |
|
c) |
Capability of handling large power |
d) |
Electrons having high mobility than holes |
|
(d) n-p-n transistor is formed by combining two |
-types crystals between which a thin 
-type crystal is there. Electrons are charge carriers within the n-p-n transistor whereas holes are charge carriers within the p-n-p transistor. Since, electrons move more easily than holes, hence n-p-n transistors are preferred compared to p-n-p.Next Question :
Consider a cylindrical element as shown in the figure. Current flowing through element is I and resistivity of material of the cylinder is 
Choose the correct option out the following

|
a) |
Power loss is second half is four times the power loss in first half |
|
b) |
Voltage drop in first is twice of voltage drop in second half |
|
c) |
Current density in both halves are equal |
|
d) |
Electric field in both halves is equal |
