2. The schematic below features a Zener diode (even though it is not the exact symbol we have been using in class) with a Zener voltage of \( 5 \mathrm{~V} \). (a) Find \( I_{S}, I_{1} \), and \( I_{L} \). (b) With all component values as shown, give the full range of values for \( R_{S} \) that would allow \( V_{L} \) to remain regulated. (c) What is the smallest possible voltage that \( V_{S} \) could supply while the circuit is still regulating and \( V_{L} \) ?
