A zener diode of power rating $\displaystyle 2$ W is to be used as a voltage regulator. If the zener diode has a breakdown of $\displaystyle 10$ V and it has to regulate voltage fluctuated between $\displaystyle 6$ V and $\displaystyle 14$ V, the value of $\displaystyle R_S$ for safe operation should be \_\_\_\_ $\displaystyle \Omega$.
