Question

The base current in common emitter mode of the transistor changes by 10 µA. If the current gain of the transistor is 50, then change in collector current is ______.

विकल्प

• 50 µA

• 0.5 mA

• 2 mA

• 2 µA

Answer 1

The base current in common emitter mode of the transistor changes by 10 µA. If the current gain of the transistor is 50, then change in collector current is 0.5 mA.

Explanation:

ΔI_B = 10 µA

β = 50 

β = `(Delta"I"_"C")/(Delta"I"_"B")`

ΔI_C =  β × ΔI_B 

= 50 × 10

= 500  µA

ΔI_C = 0.5 mA
