In the circuit shown below, current through the inductor is

The impedance looking into nodes 1 and 2 in the given circuit is

If V_A - V_B = 6 V then V_C - V_D is

With 10 V dc connected at port A in the linear nonreciprocal two-port network shown below, the following were observed:
(i) 1Ω connected at port B draws a current of 3 A
(ii) 2.5Ω connected at port B draws a current of 2 A

With 10 V dc connected at port A, the current drawn by 7Ω connected at port B is
