P-N Junction Diode

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

then the output across RL will be

Show answer and solution

Answer: (b)

The diode is forward biased when the input is $+5$ V, so $R_L$ gets $+5$ V.
When the input is $-5$ V the diode is reverse biased, no current flows, so the output is $0$ .
The output is a pulse from 0 to $+5$ V. So the answer is (b).
