For the two port network shown below, the [Y]-parameters is given as

$$[Y] = {1 \over {100}}\left[ {\matrix{ 2 & { - 1} \cr { - 1} & {4/3} \cr } } \right]S$$

The value of load impedance $$\mathrm{Z_L}$$, in $$\Omega$$, for maximum power transfer will be ___________ (rounded off to the nearest integer).

In the circuit shown below, switch S was closed for a long time. If the switch is opened at t = 0, the maximum magnitude of the voltage $$\mathrm{V_R}$$, in volts, is __________ (rounded off to the nearest integer).

The switch S$$_1$$ was closed and S$$_2$$ was open for a long time. At t = 0, switch S$$_1$$ is opened and S$$_2$$ is closed, simultaneously. The value of i$$_\mathrm{c}$$(0$$^+$$), in amperes, is

The h-parameters of a two port network are shown below. The condition for the maximum small signal voltage gain $${{{V_{out}}} \over {{V_s}}}$$ is
