Q3. Refer to the circuit below. Use two golden rules of op-amps, Ohm's Law, KCL and KVL to find (1) \( I_{1}, I_{2}, I_{3} \), and \( V_{X} \), (b) the maximum allowed value for \( R_{L} \) if Vo is not to be lower than \( -13 V \), and (c) the corresponding change in \( \mathrm{I}_{\mathrm{L}} \) and in \( \mathrm{V}_{\mathrm{O}} \) if \( \mathrm{R}_{\mathrm{L}} \) is varied in the range of \( 100 \Omega \) to \( 1 \mathrm{k} \Omega \).
