In a common -emitter transistor amplifier, an increase of `50muA` in the base current causes an increase of `1.0mA` in the collector current . Calculat gain `beta`. What will be the change in emitter current? Also calculate current gain `alpha`

A

1050 mA

B

1050 `mu`A

C

5025 mA

D

5025 `mu`A

Text Solution

Verified by Experts

The correct Answer is:
B

The change in emitter current is
`DeltaI_E=DeltaI_B+DeltaI_C=50xx10^(-6)+1xx10^(-3)`
`=1050xx10^(-6)A =1050 muA`
