Question

In a transistor, Ic = 100 mA and Ie = 100.5 mA. Find the value of Ib?

Answer 1

In that case the current gain is β = Ic/Ib = Ic / (Ie - Ic) = 100 / (100.2 - 100) = 100/0.2 = 500.

Answer 2

"Transistor"

Explanation:

DEFINITION OF TRANSISTOR:

A Transistor is a used in switch electrical signal and amplify. It is a semiconductor devices. Its used to transfer a input to the output.

GIVEN:

Ic = 100mA

Ie = 100.5

find Ib =?

Transistor formula is B= Ic / Ib,

We apply a given data in the transistor formula,

B = Ic/Ib

  = Ic/(Ie-Ic)

  =100/(100.5-100)

  =100/0.5

  =200

Hence Ib=200mA
