  1. Determine the peak value of the current through the load resistor—
    1. 2.325 mA
    2. 5 mA
    3. 1.25 mA
    4. 0 mA
Correct Option: A

Considering the given circuit for first half cycle in order to determine the peak value of the current through the load resistor.
From above figure

I =
V
Req

Where, Req = 2 || (2 + 2) =
4
kΩ.
3

Now, I =
(10 – 0.7) V
=
9.3 x 3
mA
4 / 3 kΩ4

= 6.975mA
and IL(peak) = I ×
2
= 6.975 x
2
= 2.325 mA.
