Electronics for Electricians

Stephen L. Herman was an electrician and proficient instructor with over 30 years of practical experience, and was known for his reader-friendly approach. A seasoned author, Mr. Herman wrote leading books on electricity and mathematics that are popular with students and instructors alike. For two decades, Mr. Herman served as lead instructor for the Electrical Technology Curriculum at Lee College in Baytown, Texas, where he received an Excellence in Education Award from the Halliburton Education Foundation. He also taught at Randolph Community College in Asheboro, North Carolina, for nine years and helped pioneer an electrical curriculum for Northeast Texas Community College in Mount Pleasant, Texas. His additional publications include "Electric Motor Control," "Electricity and Controls for HVAC/R," "Industrial Motor Controls," "Understanding Motor Controls," "Electronics for Electricians," "Alternating Current Fundamentals," "Direct Current Fundamentals," "Electrical Studies for Trades," "Electrical Principles," "Experiments in Electricity For Use with Lab Volt Equipment," "The Complete Laboratory Manual for Electricity" and "Practical Problems in Mathematics for Electricians."
