The secondary current arises from the action of the secondary EMF on the ( not shown ) load impedance.

For example, if an impedance Z < sub > s </ sub > is attached across the terminals of the secondary coil, it appears to the primary circuit to have an impedance of ( N < sub > p </ sub >/ N < sub > s </ sub >)< sup > 2 </ sup > Z < sub > s </ sub >.

This relationship is reciprocal, so that the impedance Z < sub > p </ sub > of the primary circuit appears to the secondary to be ( N < sub > s </ sub >/ N < sub > p </ sub >)< sup > 2 </ sup > Z < sub > p </ sub >.

Analysis may be simplified by moving the magnetizing branch to the left of the primary impedance, an implicit assumption that the magnetizing current is low, and then summing primary and referred secondary impedances, resulting in so-called equivalent impedance.

Subsequently the < sup > 3 </ sup > He flows through a secondary impedance and one side of a set of counterflow heat exchangers where it is cooled by a cold flow of < sup > 3 </ sup > He on the other side.

Care must be taken that the secondary of a current transformer is not disconnected from its load while current is flowing in the primary, as the transformer secondary will attempt to continue driving current across the effectively infinite impedance.
