# Fixator

In the theory of electrical networks, a **fixator** is a two-terminal pole through which a *fixed **current* ( constant *current **source* or constant *current *sink ) flows and at which a *fixed **voltage* ( constant *voltage source* ) drops.

For him the network equations I = const. and U = const. imprinted.

The fixator thus represents a special case of a norator (any voltage and any current ) and a nullator (U = 0 V, I = 0 A).

The fixator can also be viewed as a constant power source, in which case it must be terminated with a resistor at which the power P = U · I is converted.
