An $$N$$-channel $$JFET$$ having a pinch-off voltage $$\left( {{V_P}} \right)$$ of $$-5V$$ shows a transconductance (gm) of $$1$$ $$mA/V$$ when the applied Gate to source voltage $$\left( {{V_{GS}}} \right)$$ is $$-3V.$$ Its maximum transconductance (in $$mA/V$$) is

In the circuit of figure, the value of the base current $${{\rm I}_B}$$ will be

A $$NPN$$ Si transistor is meant for low-current audio amplification. Match is following characteristic against their values.
