Course Description

Alternating current, or AC, is the type of electrical current most commonly used in power systems worldwide. Unlike direct current, which flows in a single direction, AC alternates direction periodically. Its sinusoidal nature is advantageous for efficient power transmission and transformation. Key parameters include amplitude, frequency, and phase angle, all of which influence how AC circuits behave in practice.

What you'll learn in this course?

• Understand AC voltage and current concepts.

• Analyze single-phase and three-phase AC circuits.

• Apply Ohm’s Law and Kirchhoff’s Laws in AC circuits.

• Calculate impedance, reactance, and resonance in AC circuits.

• Understand power in AC circuits: real, reactive, and apparent power.

• Solve basic AC circuit problems using phasor diagrams.

Prerequisites

• Basic knowledge of voltage, current, resistance, and DC circuit principles

• Familiarity with algebra, trigonometry, and electrical safety is helpful
