An n-channel JFET has I_DSS = 1 mA and V_p = -5 V. Its maximum transconductance is ______

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

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

To obtain very high input and output impedances in a feedback Amplifier, the mostly used is
