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

A BJT is said to be operating in the saturation region if

A transistor having $$\alpha$$ = 0.99 and V_BE = 0.7 V, is used in the circuit of the figure.What is the value of the collector current?

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
