JEE Main 2026 — 23 January, Morning Shift — Question 36

The following diagram shows a Zener diode as a voltage regulator. The Zener diode is rated at VZ=5 V\mathrm{V}_{\mathrm{Z}}=5 \mathrm{~V} and the desired current in load is 5 mA . The unregulated voltage source can supply upto 25 V . Considering the Zener diode can withstand four times of the load current, the value of resistor RS\mathrm{R}_{\mathrm{S}} (shown in circuit) should be ____\_\_\_\_ Ω\Omega.
