In a complex network containing active voltage sources with zero internal resistances and
linear bilateral elements the open eircuit voltage across 2 terminals is 25V and the resistance
of the network viewed from the open circuited terminal is 6.25Q. If an eqivalent circuit
comprising of only a current source and impedance is made, the current source rating 18:
