Zener breakdown occurs in a $p-n$ junction having $p$ and $n$ both :

For the circuit shown below,calculate the value of ${I}_{{z}}$ : (In ${mA}$)

The reverse breakdown voltage of a Zener diode is $5.6\, V$ in the given circuit. The current $I_z$ through the Zener is......$mA$

Zener breakdown in a semiconductor diode occurs when

In the given circuit, the breakdown voltage of the Zener diode is $3.0 \, V$. What is the value of $I_z$ (in $ \, mA$)?

$A$ Zener diode voltage regulator operated in the range $120 \, V - 180 \, V$ produces a constant supply of $110 \, V$ and $250 \, mA$ to the load. If the maximum current is equally shared between the load and the Zener diode, then the values of load resistance $(R_L)$ and series resistance $(R_S)$ are respectively
