Question

1. which component is used to change alternating current to direct current? (1 point)

a capacitor
a transistor
a diode
an integrated circuit

Explanation:

A diode allows current to flow in only one direction. In the case of alternating current (AC), which changes direction periodically, a diode can be used in a rectifier circuit. A rectifier circuit with diodes takes the AC input and converts it to direct current (DC) (current that flows in one direction). A capacitor stores electrical energy in an electric - field. A transistor is used for amplification or switching of electronic signals. An integrated circuit is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material.

Answer:

a diode
