The value of the resistor, $R_{S}$ , needed in the DC voltage regulator circuit shown here, equals:

Options:

Answer:

Solution:

Across zener diode $V_{L} = c o n s t a n t$

$∵ V_{i} = V_{L} + (n + 1) I_{L} R_{S}$

$\Rightarrow V_{i} - V_{L} = (n + 1) I_{L} R_{S}$

$\Rightarrow R_{S} = \frac{V_{i} - V_{L}}{(n + 1) I_{L}}$
