Course Description

Alternating current, or AC, is a type of electrical current in which the flow of charge periodically reverses direction, in contrast to direct current, which flows in a single direction. AC is the standard form of electricity supplied to homes, offices, and industries worldwide. The frequency of AC, measured in hertz, is 50 Hz in most countries or 60 Hz in others, such as the United States. AC systems offer distinct advantages over DC, particularly in the ease of voltage transformation using transformers, and the efficiency of long-distance power transmission. Understanding AC fundamentals is essential for designing and analyzing circuits, motors, transformers, and other electrical systems.

What you'll learn in this course?

• Understand the fundamental concepts of alternating current (AC).

• Analyze AC voltage and current in resistive, inductive, and capacitive circuits.

• Calculate impedance, phase angles, and power in AC circuits.

• Differentiate between single-phase and three-phase systems.

• Apply knowledge to practical AC system analysis in engineering applications.
