Questions & Step-by-Step Solutions

What is the function of a rectifier in a power supply?
  • Step 1: Understand that electricity can come in two forms: alternating current (AC) and direct current (DC).
  • Step 2: Know that AC is the type of electricity that changes direction, while DC flows in one direction.
  • Step 3: Learn that a rectifier is a device used in power supplies.
  • Step 4: Recognize that the main job of a rectifier is to change AC into DC.
  • Step 5: Conclude that this conversion is important because many electronic devices need DC to operate.
