What component changes AC to DC?

Transformer
Capacitor
Inductor
Rectifier

The correct answer is: Rectifier

A transformer converts the voltage level of an alternating current, but does not change AC to DC. A capacitor is used to temporarily store and release electrical energy, but it does not convert AC to DC. An inductor is used to store and release energy in a magnetic field, but it does not change AC to DC. A rectifier, on the other hand, is a component that converts AC to DC by using diodes to allow current to flow in only one direction. Therefore, the correct answer is D.
