Current gain for an npn CE configuration transistor is when the reading are shown in the graph –

A

2

B

2 × 10–3

C

0.5

D

500

Answer

500

Explanation

Solution

b = ΔICΔIb\frac { \Delta \mathrm { I } _ { \mathrm { C } } } { \Delta \mathrm { I } _ { \mathrm { b } } } = (21)×103(42)×106\frac { ( 2 - 1 ) \times 10 ^ { - 3 } } { ( 4 - 2 ) \times 10 ^ { - 6 } } = 12\frac { 1 } { 2 }× 1000 = 500
