In the case of a common emitter transistor amplifier, the

In the case of a common emitter transistor amplifier, the ratio of the collector current to the emitter current I_c /I_e is 0.96. The current gain of the amplifier is

	I_c	= 0.96
	I_e

⇒ I_c = 0.96 I_e
But I_e = I_c + I_b = 0.96I_e + I_b
⇒ I_b = 0.04 I_e
∴ Current gain,

β =	I_c	=	0.96 I_e	= 24
	I_b		0.04 I_e
