Crossover distortion behavior is characteristic of

The circuit shown, the figure supplies power to on 8 v speaker or L.S. The vaLUES OF $${I_C}$$ and $${V_{CE}}$$ for this ciruit will be

A power Amplifier delivers 50 W output at 50% efficiency. The ambient temperature is 25$$^\circ $$ C. if the maximum allowable junction temperature is 150 $$^\circ $$ C, then the maximum thermal resistance $${\theta _{Jc}}$$ that can be tolerated is

A class-A transformer coupled, transistor power Amplifier is required to deliver a power rating of the transistor should not be less than.
