Question

With $\text{10 V}$ dc connected at port $\text{A}$ in the linear nonreciprocal two-port network shown below, the following were observed:

1. $\text1\;\Omega$ connected at port $\text{B}$ draws a current of $\text{3 A}$
2. $\text2.5\;\Omega$ connected at port $\text{B}$ draws a current of $\text{2 A}$

With $\text{10 V}$ dc connected at port $\text{A}$, the current drawn by $\text{7}\;\Omega$ connected at port $\text{B}$ is

• A. $\frac{3}{7}\;\text{A}$
• B. $\frac{5}{7}\;\text{A}$
• C. $\text{1 A}$
• D. $\frac{9}{7}\;\text{A}$
