Conversion of alternating current to direct current is called:

Correct answer: B. Rectification

  • A. Amplification
  • B. Rectification
  • C. Modulation
  • D. Both B & C

Explanation

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC). Option B is correct as Rectification is the process of converting alternating current (AC) to direct current (DC). This is typically done using a device called a rectifier, which allows current to flow in only one direction.

About Alternating Current

Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
