An industrial standard for more than 30 years, Alternating Current Fundamentals has been updated once again to furnish readers with the most comprehensive information available on AC essentials. Topics are thoughtfully arranged to build knowledge, progressing from basic principles such as the differences between peak, rms, and average values to more complex coverage of circuits containing resistance, inductance, and capacitance. The 7th Edition features improved graphics that assist readers in understanding such state-of-the-art concepts as phase angle differences between voltage and current in an alternating current circuit, apparent power versus true power, and the power factor.
