A common emitted amplifier circuit, built using an npn transistor, is shown in the figure. Its dc current gain is `250,R_(C)=1Komega` and `V_(C C)=10V`. What is the minimum base current for `V_(CE)` to reach saturation?

In the common emitter amplifier circuit, Fig. an npn transistor with output voltage of the amplifier as 1 V, the current gain of transistor amplifier is :
