Consider the emitter-follower amplifier shown in Figure P8.13. An average power of \(0.5 \mathrm{~W}\) is to be delivered to a load of \(R_{L}=8 \Omega\).

(a) What are the peak values of ac output voltage and ac load current?

(b) The minimum collector current occurs when \(V_{O}\) reaches the maximum negative value. If the minimum collector current is to be 10 percent of \(I_{O}\), determine \(I_{O}\). (Use the results of part (a).)
