The relation between the energy of photons and the intensity of photons is, hv=nIA, where n is the number of photons, if we increase the number of photons then frequency does not change it means total energy and kinetic energy of photon remains unchanged but due to to this property the intensity of light is increased.
In a photoelectric experiment, increasing the intensity of incident light:

The following diagram shows a Zener diode as a voltage regulator. The Zener diode is rated at $V_{z}=5 \mathrm{~V}$ 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 $R_{S}$ (shown in circuit) should be $\_\_\_\_$ $\Omega$.
