Answer / lucky singla

because collector-base junction has more resistance than
the emitter-base junction so, majorty of charge carriers
will move in to the emitter region & minority of charge
carriers will move in to the collector region &collector of
other transistor will get more chage carriers but they do
not remain in it and moves in to the base region and a
thick layer of depletion region is formed in it
