Chapter 8, Problem 8.34P

The parameters for the transformer−coupled common−emitter circuit in Figure P8.33 are $V_{CC}=36\text{V}$ and $n_1:n_2=4:1$ . The signal power delivered to the load is 2W. Determine: (a) the rms voltage across the load; (b) the rms voltage across the transformer primary; and (c) the primary and secondary currents. (d) If $I_{CQ}=150\text{mA}$ , what is the conversion efficiency?
