Electric circuits miscellaneous

  1. A certain network consists of two ideal voltage sources and a large number of ideal resistors. The power consumed in one of the resistor is 4 W when either of the two sources is active and the other is replaced by a short circuit. The power consumed by the same resistor when both the sources are simultaneously active would be
    1. zero or 16 W
    2. 4 W or 8 W
    3. zero or 8 W
    4. 8 W or 16 W
Correct Option: C

The power consumed by the same resistor will be either 4 – 4 = 0 W; or 4 + 4 = 8 W.
