HOW THE ELECTRIC CURRENT IS TRANSFORMED.
=133.
Electric Current and Work.= The amount of work a current can do depends upon two factors; the strength (amperes), and the pressure, or E. M. F. (volts).
A current of 10 amperes with a pressure of 1,000 volts = 10 × 1,000 = 10,000 watts.
This furnishes the same amount of energy as a current of 50 amperes at 200 volts; 50 × 200 = 10,000 watts.

Chapter 20 of Things a Boy Should Know About Electricity by Thomas M. (Thomas Matthew) St. John holds 45 sentences, grouped into 9 reading sections of at most 5 sentences.

What does chapter 20 of Things a Boy Should Know About Electricity contain?

Chapter 20 holds 45 sentences of Things a Boy Should Know About Electricity, unabridged, divided into 9 reading sections.

This page carries chapter 20 of Things a Boy Should Know About Electricity by Thomas M. (Thomas Matthew) St. John exactly as it stands in the source edition, without abridgement. It runs to 45 sentences, grouped into 9 sections of at most 5 sentences so that a reader can take the chapter in steady, finishable pieces. The chapter also stores a coverage record mapping every one of its sentences to a part of the work, which is how the edition demonstrates that no line was dropped.

How do I study chapter 20 of Things a Boy Should Know About Electricity?

Work through the 9 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 9 sections in this chapter is short enough to read once, hear once, and then re-read with the vocabulary in view. Tapping a word plays it alone and opens its dictionary entry with IPA, part of speech and meaning, so the reader is never forced to guess a pronunciation from spelling. Working section by section keeps a long chapter from becoming an undifferentiated wall of text, which is the usual reason a reader abandons a work of this period.

Can chapter 20 be read aloud to me?

Yes — every sentence and every individual word in chapter 20 can be played aloud in United States English.

Audio covers the whole chapter: any sentence can be played, and any single word within it can be played on its own. The voice uses United States English. For a work of this period that matters, because spelling is an unreliable guide to pronunciation for vocabulary that has fallen out of daily use, and a learner who guesses wrong tends to keep the error. Hearing the word in its own sentence, and then alone, settles it.
