In the given circuit, the two-port network has the impedance matrix $[Z]=\left[\begin{array}{cc}40 & 60 \\ 60 & 120\end{array}\right]$. The value of $Z_L$ for which maximum power is transferred to the load is $\_\_\_\_$ $\Omega$.

$$ \text { In the circuit shown below, the Thevenin voltage } V_{\text {th }} \text { is } $$

The current in the RL - circuit shown below is $i(t)=10 \cos (5 t-\pi / 4) \mathrm{A}$. The value of the inductor (rounded off to two decimal places) is $\_\_\_\_$ H.

In the circuit shown below, all the components are ideal and the input voltage is sinusoidal. The magnitude of the steady - state output $V_0$ (rounded off to two decimal places) is $\_\_\_\_$ V.
