Explain the working of reverse biased $\mathrm{p}-\mathrm{n}$ junction diode with the help of circuit diagram. How is it used in Zener diode?

An ac voltage of peak value $30 \mathrm{V}$, is connected in series with a germanium diode and a load resistor of $400 \mathrm{\Omega }$. The forward resistance of the diode is $20 \mathrm{\Omega }$ and the barrier voltage is $0.3 \mathrm{V}$. Find the peak current through the diode and peak voltage across the load. What will happen to these values, if the diode is assumed to be ideal ?

Explain the working process of full wave rectification of $(\mathrm{p}-\mathrm{n})$ junction diode.
