Networks Analysis and Synthesis

Q1: A certain network has two ideal voltages sources and a large number of ideal resistances. The power consumed in one of the resistances is 4 W when either of two sources is active and the other source is active and the other source is short circuited. When both sources is short circuited.When both sources are active, the power consumed in the same resistor would be

A zero or 16 W

B 4 W or 8 W

C zero or 8 W

D 8 W or 16 W

ANS:A - zero or 16 W

If currents of both sources add, total current would be twice and power is four time, i.e., 16 W. If currents subtract, net current and power are zero.
