Welcome to AC Circuits
This module explores Alternating Current (AC) circuits, where voltage and current periodically reverse direction. Understanding AC is crucial for analyzing power systems, communications, and many mechatronic applications. Here, you'll interact with concepts like phasors, impedance, and AC power, transforming complex theory into tangible insights through hands-on visualization and simulation.
Learning Objectives
- Describe the characteristics of sinusoidal waveforms.
- Calculate reactance and impedance for R, L, and C components.
- Analyze AC circuits using phasors.
- Differentiate between real, reactive, and apparent power.
