acts in series and in parallel circuits and how the voltage an current are measured. In this lesson we have considered only the elementary circuits used in electrical work and Radio; more complete circuits will be studied in future lessons. Your knowledge of Radio is increasing quite rapidly, and with each lesson we dig deeper into the great storehouse of interesting information and knowledge the study of Radio opens up for us.
