A zener diode voltage regulator operated in the range 120 - 180 V produces a constant supply of 110 V and 250 mA to the load. If the maximum current is to be equally shared between the load and zener, then the value of series resistance $(R_S)$ and load resistance (R_L)$ are :

$\begin {array} {1 1} (1)\;R_L = 70 \Omega;R_S=280\Omega & \quad (2)\;R_L = 440 \Omega;R_S=140\Omega \\ (3)\;R_L = 140 \Omega;R_S=440\Omega & \quad (4)\;R_L = 280 \Omega;R_S=70\Omega \end {array}$

Can you answer this question?
