QUESTION #37 Zener Diode
The following diagram shows a Zener diode as a voltage regulator. The Zener diode is rated at V_Z = 5V and the desired current in load is 5 mA. The unregulated voltage source can supply up to 25V. Considering the Zener diode can withstand four times of the load current, the value of resistor R_S (shown in circuit) should be ____ Omega. {{IMG1}}
