What is a Zener diode?

For the voltage regulator circuit using Zener diode shown in figure below, the current flowing through the Zener diode is $10 \mathrm{mA}\le i \le 100 \mathrm{mA}$. Find the range of load current $i_L$ and range of load resistance $R_L$ to be connected at the output.

During reversed biased the voltage may be increased to such a value so that valence electrons are pulled from the host atoms. These electrons account for high current and cause breakdown. The emission of electrons from the host atoms due to high electric field is known as internal field emission or field ionization. The electric field required for field ionization is
