It can increase or decrease the value of capacitor, an inductor or resistance in AC circuits i.e. a transformer thus acts as an impedance transferring device. It can be used to prevent DC from passing from one circuit to the other. In other words, they are used as ripple filters which compensate for the pulsating DC.
