Question

A Zener diode with a breakdown voltage of $4 V$ is connected in series with a resistance $R$ to a battery of emf $10 V$ . The maximum power dissipation rating for the Zener diode is $1 W$ . The value of $R$ to ensure maximum power dissipation across the diode is

Options:

Answer:

B

Solution:

$P_{zener} = 4 i = 1$

$\Rightarrow i = \frac{1}{4} A$

$i = \frac{6}{R} = \frac{1}{4}$

$\Rightarrow R = 24 Ω$
