Consider the circuit shown in Figure P17.42. Neglect base currents and assume \(V_{B E}\) (on) \(=0.7 \mathrm{~V}\) and \(V_{\gamma}=0.3 \mathrm{~V}\).

(a) Determine \(i_{E}\) for \(v_{X}=v_{Y}=3 \mathrm{~V}\).

(b) Determine \(i_{E}\) and \(R_{C}\) for \(v_{X}=v_{Y}=2.4 \mathrm{~V}\) such that \(v_{O}=2.4 \mathrm{~V}\).

(c) Using the results of parts (a) and (b), determine the power dissipated in the circuit for (i) \(v_{X}=v_{Y}=3 \mathrm{~V}\) and (ii) \(v_{X}=v_{Y}=2.4 \mathrm{~V}\).
