Symmetrical Reactance Chart
May 1959 Electronics World

May 1959 Electronics World

May 1959 Electronics World Cover - RF Cafe Table of Contents 

Wax nostalgic about and learn from the history of early electronics. See articles from Electronics World, published May 1959 - December 1971. All copyrights hereby acknowledged.

Reactance charts were a dime a dozen (free, actually) and appeared as regular features in electronics magazines in the days before smartphone apps provided ready access to reactance versus frequency calculations. This one was in the May 1959 issue of Electronics World. Calculators are nice and indispensible in design work, but sometimes having "the big picture" of how various values of inductance and capacitance "react" with changes in applied frequency is often useful - especially if you are a newcomer to electronics. To paraphrase a popular saying, "A reactance chart is worth a thousand calculators."
