In an experiment of CE configuration of n-p-n transistor, the transfer characteristics are observed as given in figure.

If the input resistance is 200 $$\Omega$$ and output resistance is 60 $$\Omega$$, the voltage gain in this experiment will be ____________.

In the given circuit, the value of current I_L will be ____________ mA. (When R_L = 1k$$\Omega$$)

A transistor is used in common-emitter mode in an amplifier circuit. When a signal of 10 mV is added to the base-emitter voltage, the base current changes by 10 $$\mu$$A and the collector current changes by 1.5 mA. The load resistance is 5 k$$\Omega$$. The voltage gain of the transistor will be _________.
