${V_T} = \frac{{{V_1}}}{{{A_1}{A_2}}},{Z_T} = \frac{{{A_1}{B_2} + {B_1}{D_2}}}{{{A_1}{A_2} + {B_1}{C_2}}}$

TuteeHUB · Answer

${V_T} = \frac{{{V_1}}}{{{A_1}{A_2} + {B_1}{C_2}}},{Z_T} = \frac{{{A_1}{B_2} + {B_1}{D_2}}}{{{A_1}{A_2}}}$

TuteeHUB · Answer

${V_T} = \frac{{{V_1}}}{{{A_1} + {A_2}}},{Z_T} = \frac{{{A_1}{B_2} + {B_1}{D_2}}}{{{A_1} + {A_2}}}$

1.	Two passive two-port networks are connected in cascade as shown in figure. A voltage source is connected at port 1.Given V1 = A1V2 + B1I2I1 = C1V2 + D1I2V2 = A2V3 + B2I3I2 = C2V3 + D2I3A1, B1, C1, D1, A2, B2, C2, and D2 are the generalized circuit constants. If the Thevenin equivalent circuit at port 3 consists of a voltage source VT and an impedance ZT connected in series, then
A.	\({V_T} = \frac{{{V_1}}}{{{A_1}{A_2}}},{Z_T} = \frac{{{A_1}{B_2} + {B_1}{D_2}}}{{{A_1}{A_2} + {B_1}{C_2}}}\)
B.	\({V_T} = \frac{{{V_1}}}{{{A_1}{A_2} + {B_1}{C_2}}},{Z_T} = \frac{{{A_1}{B_2} + {B_1}{D_2}}}{{{A_1}{A_2}}}\)
C.	\({V_T} = \frac{{{V_1}}}{{{A_1} + {A_2}}},{Z_T} = \frac{{{A_1}{B_2} + {B_1}{D_2}}}{{{A_1} + {A_2}}}\)
D.	\({V_T} = \frac{{{V_1}}}{{{A_1}{A_2} + {B_1}{C_2}}},{Z_T} = \frac{{{A_1}{B_2} + {B_1}{D_2}}}{{{A_1}{A_2} + {B_1}{C_2}}}\)
