If a `p-n` junction diode, a square input signal of `10 V` is applied as shown.

Then the out put signal across `R_(L)` will be
.

Options

A.
B.
C.
D.

Answer

C

Explanation

During the positive half cycle, the p-n junction is forward biased, offers minimum resistance. Hence, we get output across `R_(L)`. During the negative half cycle, p-n junction is reverse biased, offers maximum resistance, hence no output across `R_(L)`.
