A Zener diode is connected as a voltage regulator. The Zener diode is rated at VZ = 5V and the desired current in the load resistor is 5 mA. The unregulated DC voltage source supplies up to 25V. Given that the Zener diode can safely withstand a maximum current equal to four times the load current, what should be the minimum value of the series resistor RS to prevent damage at maximum input voltage?
