Suppose an unregulated d.c. input voltage

{V_I}

is applied to a Zener diode having breakdown voltage

\left( {{V_z}} \right)

. Then the breakdown condition for the diode to work as voltage regulator is

View answer and explanation

Correct option: C

{V_I} > {V_z}

Option C (

{V_I} > {V_z}

) is correct because the input voltage must be greater than the Zener voltage for the diode to operate in the breakdown region and regulate the voltage.
