Master alternating currents with hands-on experiments from a classic lab manual. This practical guide shows how to observe, measure, and reason about AC circuits using clear, step-by-step experiments. It assumes basic knowledge of direct currents and magnetism and is designed for a supple, classroom-friendly approach.

The book gathers a sequence of beginner-friendly experiments that build from distinguishing AC and DC to exploring inductance, resistance, frequency, and power in AC systems. It emphasizes laboratory work, data collection, and plotting results to help you understand how real components behave under alternating current. Though published in 1915, the techniques reflect foundational methods in electrical engineering education and remain a useful reference for hands-on learning.

- Learn to tell alternating current from direct current with simple observations of a lamp’s behavior near a magnet.
- Measure voltages, currents, and resistances in inductors, chokes, and condenser circuits across different frequencies.
- Build and analyze vector diagrams to visualize phase relationships between current and voltage.
- Explore practical concepts like impedance, transmission line behavior, and three-phase systems through guided experiments.

Ideal for students of electrical engineering, instructors creating lab curricula, and readers seeking a historical, hands-on look at early AC experimentation and instrumentation.
