Transformer Coupled class A is operating with $V_{CC}=10V,R_L=8,$ and transformer turn ration $n=3$ icasurements at $V_{CE}$ gives $V_{\text{C}\text{E}\text{m}\text{i}\text{n}}=1\mathrm{.}7V$ and $V_{\text{C}\text{E}\text{m}\text{a}\text{x}}=18\mathrm{.}3V,$ and measurements at $l_c$ gives $l_{\text{m}\text{i}\text{n}}=25$ mA and $I_{\text{C}\text{m}\text{a}\text{x}}=255mA.$
