2.32 The circuit in Fig. P2.32 utilizes an ideal op amp. (a) Find \( I_{1}, I_{2}, I_{3}, I_{L} \), and \( V_{x} \). (b) If \( V_{o} \) is not to be lower than \( -13 \mathrm{~V} \), find the maximum allowed value for \( R_{L} \). (c) If \( R_{L} \) is varied in the range \( 100 \Omega \) to \( 1 \mathrm{k} \Omega \), what is the corresponding change in \( I_{L} \) and in \( V_{o} \) ?
