Correct answer
300
Step-by-step explanation
Given Zener voltage V and maximum power dissipation W.
The maximum safe current through the Zener diode is given by A.
The voltage drop across the series resistor is V.
For safety, the current through the circuit should not exceed . Thus, the minimum resistance is .
Answer:
