1V/10 mA = 10 W
(b) From the curve at V = –10 V, I = –1 mA,
Therefore,
rrb = 10 V/1mA= 1 0 × 107 W

14 7  APPLICATION OF JUNCTION DIODE AS A RECTIFIER
From the V-I characteristic of a junction diode we see that it allows current
to pass only when it is forward biased So if an alternating voltage is
applied across a diode the current flows only in that part of the cycle
when the diode is forward biased
