Question

alpha of transistor is 0.9.calaculate bita.​

Answer 1

Answer:

Explanation:

The Common Emitter Amplifier Circuit

A transistors current gain is given the Greek symbol of Beta, ( β ). As the emitter current for a common emitter configuration is defined as Ie = Ic + Ib, the ratio of Ic/Ie is called Alpha, given the Greek symbol of α. Note: that the value of Alpha will always be less than unity.
