$$\begin{array}{l}Given:\\V_1=A_1V_2+B_1I_2\\I_1=C_1V_2+D_1I_2\\V_2=A_2V_3+B_2I_3\\I_2=C_2V_3+D_2I_3\end{array}$$

$$A_1,\;B_1,\;C_1,\;D_1,\;A_2,\;B_2,\;C_2,\;and\;D_2$$ are the generalized circuit constants. If the Thevenin equivalent circuit at port 3 consists of a voltage source V_T and impedance Z_T connected in series, then

$$V_T=\frac{V_1}{A_1A_2},\;Z_T=\frac{A_1B_2+B_1D_2}{A_1A_2+B_1C_2}$$

$$V_T=\frac{V_1}{A_1A_2+B_1C_2},\;Z_T=\frac{A_1B_2+B_1D_2}{A_1A_2}$$

$$V_T=\frac{V_1}{A_1+A_2},\;Z_T=\frac{A_1B_2+B_1D_2}{A_1+A_2}$$

$$V_T=\frac{V_1}{A_1A_2+B_1C_2},\;Z_T=\frac{A_1B_2+B_1D_2}{A_1A_2+B_1C_2}$$

In a linear two-port network, when 10 V is applied to Port 1, a current of 4 A flows through Port 2 when it is short-circuited. When 5V is applied to Port1, a current of 1.25 A flows through a 1 Ω resistance connected across Port 2. When 3V is applied to Port 1, then current (in Ampere) through a 2 Ω resistance connected across Port 2 is _________.
