A \(5.0 \mathrm{~V}\) stabilized power supply is required to be designed using a \(12 \mathrm{~V}\) DC power supply as input source. The maximum power rating of zener diode is \(2.0 \mathrm{~W}\). The minimum value of resistance \(R_{\mathrm{s}}\) in \(\Omega\) connected in series with zener diode will be
