Question

The base current ib = 10ua emitter current = 1.20ma determine the beta alpha Ic​

Answer 1

Answer:

The common base DC current gain is a ratio of the value of the transistor's collector current to the value of the transistor's emitter current, i.e.

---(1)

Also, the common-emitter current gain is the ratio of the value of the transistor's collector current to the value of the transistor's base current in a transistor, i.e.

---(2)

Using Equation (1) and (2), we get:

For a transistor, the relation between the collector, base, and emitter current is:

IE = IB + IC

IC = β IB

IE = (β + 1) IB
