beta is never bigger than one so ib when multiplied be beta it will decrease .

but i found that is used to separate two circuits so the current begin one the first circ on low r and goes to another circ with big r ( r = resistor )
how transistor amplifies the current when I(emitter) = I (base)+ I(collector) , do the mean by amplifying is controlling the current like the current in circ. is 10 A and then reduce it to 5 and then amplify it to 10 again ?
