12.4 For the class B output stage of Fig. 12.6, let VCC =6V and RL =4 Ω. If the output is a sinusoid with 4.5-V peak amplitude, find (a) the output power; (b) the average power drawn from each supply; (c) the power efficiency obtained at this output voltage; (d) the peak currents supplied by vI, assuming that βN =βP =50; and (e) the maximum power that each transistor must be capable of dissipating safely. (a) 2.53 W; (b) 2.15 W; (c) 59%; (d) 22.1 mA; (e) 0.91 W
