The Progress Check Booklet is designed to be used by the student working in the programed course to determine if he has mastered the concepts in the course booklets on: electrical current; voltage; resistance; measuring current and voltage in series circuits; relationships of current, voltage, and resistance; parellel circuits; combination circuits and voltage dividers, induction; relationships of current, counter EMF (electromotive force), and voltage in LR (inductive resistance) circuits; transformers; capacitance; series AC (alternating current) resistive-reactive circuits; series AC, RLC (inductive-resistive-capacitive) circuits and resonance; and parallel AC resistive-reactive circuits. Each progress check lesson consists of self-tests with the accompanying answers. Correct answers to all questions indicate to the student that he is ready to proceed to the next lesson. Appended are trigonometric tables and a summary of each of the modules. (Author/BP)
