The IdealTransformer is a two-port component with resistive (not inductive!) behaviour. The left port voltage phasor v1, the left port current phasor i1, the right port voltage phasor v2, and the right port current phasor i2 are connected by the following relations:
v1 = n*v2,
i2 = -n*i1.
The turns ratio n has a constant real (but usually integer) value.
