Part of Speech

Noun

Phonetic Transcription

/ˈæb.sə.luːt ˈɡæl.və.nɑː.mɚ/

Meaning

An absolute galvanometer is an electrical instrument used to measure direct current (DC) or the total current in a circuit. It functions by measuring the magnetic field produced by the electric current and can provide accurate readings regardless of the circuit's configuration or the resistance in the circuit. This makes it a valuable tool in both laboratory settings and practical electrical engineering.

Usage

The term is primarily used in technical and scientific contexts, particularly in physics and electrical engineering. It is more prevalent in written contexts such as academic papers, technical manuals, and textbooks than in everyday spoken language.

Frequency of Use

The term often appears in specialized discussions about electrical measurement and is not commonly used in casual conversation.

Example Sentences

1. The researcher utilized an absolute galvanometer to measure the current in their experiment.

2. Исследователь использовал абсолютный гальванометр для измерения тока в своем эксперименте.

3. In this lab, we learned how to calibrate an absolute galvanometer for accurate readings.

4. На этой лабораторной работе мы научились калибровать абсолютный гальванометр для получения точных показаний.

5. Understanding the principles behind an absolute galvanometer is essential for electrical engineering students.

6. Понимание принципов работы абсолютного гальванометра является необходимым для студентов электротехнических специальностей.

Idiomatic Expressions

The term "absolute galvanometer" itself does not appear in common idiomatic expressions. However, related concepts in physics and measurements can lead to relevant phrases.

1. "Throwing in the towel" can also apply to a situation where a galvanometer fails to provide accurate readings due to improper setup.

2. «Сдаться» также можно сказать о ситуации, когда гальванометр не дает точных показаний из-за неправильной настройки.

3. "Bending the rules" could refer to adjusting measurements unduly, similar to adjusting settings on an absolute galvanometer to show desired results.

4. «Нарушение правил» может означать произвольную корректировку измерений, как настройка абсолютного гальванометра для получения желаемых результатов.

Etymology

The word galvanometer is derived from the name of Italian scientist Luigi Galvani, who discovered that muscle contractions can be caused by electric current. The prefix "absolute" indicates that the instrument provides a definitive measurement independent of external factors like the internal resistance of the circuit.

Synonyms and Antonyms

Synonyms: - Current meter - Amperemeter

Antonyms: - None specific, as it is a specialized instrument without direct oppositional counterparts in terminology.
